Check Digit Verification of cas no

The CAS Registry Mumber 81206-50-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,2,0 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81206-50:
(7*8)+(6*1)+(5*2)+(4*0)+(3*6)+(2*5)+(1*0)=100
100 % 10 = 0
So 81206-50-0 is a valid CAS Registry Number.

Preparation method of benzyl iodide and derivatives thereof

-

Paragraph 0065-0069, (2020/06/09)

The invention discloses a preparation method of benzyl iodide and derivatives thereof. The preparation method comprises the following steps: under the reduction action of sodium borohydride, a benzylalcohol compound shown as a formula I reacts with elemental iodine to obtain benzyl iodide shown as a formula II and derivatives thereof; in the formula I and the formula II, R represents one or moresubstituents on a benzene ring and is selected from at least one of aryl, substituted or unsubstituted alkyl, halogen and nitro. The preparation method of benzyl iodide and derivatives thereof is scientific and reasonable, sodium borohydride which is mild in reactivity, low in price and easily available is used as a reducing agent, and elemental iodine is convenient and easily available; in addition, the preparation method has the characteristics of simplicity and convenience in operation, high synthesis yield, easiness in product purification, environmental friendliness and the like.

Application of "click" chemistry in solid phase synthesis of alkyl halides

Das, Diparjun,Chanda, Tridib,Rokhum, Lalthazuala

, p. 775 - 783 (2016/01/20)

A convenient and highly selective microwave assisted procedure for the conversion of allylic, benzylic and aliphatic alcohols to their corresponding halides using polymer-bound triphenylphosphine and iodine is presented. In case of symmetrical diols, mono-iodination product is obtained in very high yield. Additionally, highly regioselective behavior is observed in our procedure. Simplicity in operation, no column chromatography required for the purification of the products, recyclability of the reagents used, short reaction times and good to excellent yields are the advantages of our protocol. Most functional groups remain unaffected under our reaction condition.

Ionic liquid-induced conversion of methoxymethyl-protected alcohols into nitriles and iodides using [Hmim][NO3]

Noei, Jalil,Mirjafari, Arsalan

supporting information, p. 4424 - 4426 (2014/08/05)

This Letter reports a one-pot efficient conversion of methoxymethyl-ethers into their corresponding nitriles and iodides using the ionic liquid, 1-methyl-3H-imidazolium nitrate ([Hmim][NO3]) under microwave irradiation. A variety of products were prepared in high yields using this method.
