Check Digit Verification of cas no

The CAS Registry Mumber 136814-65-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,8,1 and 4 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 136814-65:
(8*1)+(7*3)+(6*6)+(5*8)+(4*1)+(3*4)+(2*6)+(1*5)=138
138 % 10 = 8
So 136814-65-8 is a valid CAS Registry Number.

Boron-Promoted Ether Interchange Reaction: Synthesis of Alkyl Nitroaromatic Ethers from Methoxynitroarenes

, p. 702 - 707 (2020/02/11)

The first protocol for boron-promoted ether interchange reaction of methoxynitroarenes was described. A series of methoxynitroarenes and alcohols, including primary, secondary, as well as tertiary alcohols were reacted smoothly in moderate to good yields under the optimized reaction conditions. This protocol constitutes an operationally simple and scalable strategy for the synthesis of alkyl nitroaromatic ethers. Moreover, the new reactivity of boron reagents was discovered.
