Check Digit Verification of cas no

The CAS Registry Mumber 86943-12-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,9,4 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 86943-12:
(7*8)+(6*6)+(5*9)+(4*4)+(3*3)+(2*1)+(1*2)=166
166 % 10 = 6
So 86943-12-6 is a valid CAS Registry Number.

Diastereoselective α Allylation of Secondary and Tertiary Thioamides via Thio-Claisen Rearrangement. A Structural Proof of Z Secondary Thioamide Dianions and Z Tertiary Thioamide Anions

Tamaru, Y.,Furukawa, Y.,Mizutani, M.,Kitao, O.,Yoshida, Z.

, p. 3631 - 3639 (2007/10/02)

Highly diastereoselective α allylation of secondary and tertiary thioamides is achieved by making use of thio-Claisen rearrangement.From the correlation between the diastereoselectivities in products and the structures of allylating agents, the Z structures of secondary thioamide dianion (ca. 100percent Z) and tertiary thioamide anion (>97percent Z) are concluded.
