Check Digit Verification of cas no

The CAS Registry Mumber 195298-97-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,2,9 and 8 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 195298-97:
(8*1)+(7*9)+(6*5)+(5*2)+(4*9)+(3*8)+(2*9)+(1*7)=196
196 % 10 = 6
So 195298-97-6 is a valid CAS Registry Number.

Synthetic Study of Selective Benzylic Oxidation

Wang, Wuyi,Li, Tiechao,Attardo, Giorgio

, p. 6598 - 6602 (1997)

Oxidation of bisbenzyl ethers was studied using 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ). Compared to other benzylic oxidations such as Kornblum type reaction of benzyl bromides or MnO2 oxidation of benzyl alcohols, DDQ oxidation offered advantages of being mild and highly selective to provide monoaldehyde products. We have explored factors which influence the course of the reaction and exemplified the synthetic value of the approach by preparing a number of aromatic intermediates (7-8, 15-25).
