72445-15-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 72445-15-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,4,4 and 5 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 72445-15:
(7*7)+(6*2)+(5*4)+(4*4)+(3*5)+(2*1)+(1*5)=119
119 % 10 = 9
So 72445-15-9 is a valid CAS Registry Number.

Direct preparation of allylstannanes from allyl alcohols: Convenient synthesis of β-substituted allylstannanes and of stereodefined γ-substituted allylstannanes

Weigand, Stefan,Brueckner, Reinhard

, p. 475 - 482 (2007/10/03)

Primary allyl alcohols are converted into allyltributylstannanes in a one-pot operation. It entails (i) deprotonation with BuLi, (ii) sulfonylation with mesyl chloride, and (iii) nucleophilic substitution by LiSnBu3. Conversions are quantitative with isolated yields ranging from 70% to 100%. If the starting allyl alcohol contains a stereogenic double bond its configuration is retained.

PREPARATION AND DIELS-ALDER REACTIONS OF SOME FUNCTIONALIZED ISOPRENES

Mandai, Tadakatsu,Yokoyama, Haruyuki,Miki, Toshio,Fukuda, Haruo,Kobata, Hiroshi,et al.

, p. 1057 - 1060 (2007/10/02)

A convenient synthetic method for some functionalized isoprenes employing 1-bromo-2-phenylthioethane and ethyl acetoacetate as starting materials is reported.It has also been found that the dienes thus obtained gave functionalized limonene analogs by Diel
