Check Digit Verification of cas no

The CAS Registry Mumber 139615-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,1 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 139615-68:
(8*1)+(7*3)+(6*9)+(5*6)+(4*1)+(3*5)+(2*6)+(1*8)=152
152 % 10 = 2
So 139615-68-2 is a valid CAS Registry Number.

Stereoselective synthesis of (3E,5E)-dien-2-ones and (2E,4E)-dienals via 2-phenylsulfonyl 1,3-dienes

Baeckvall, Jan-E.,Ericsson, Anna M.,Plobeck, Niklas A.,Juntunen, Seppo K.

, p. 131 - 134 (2007/10/02)

Michael addition of nitroalkanes to 2-phenylsulfonyl 1,3 dienes proceeded smoothly in the presence of DBU to give nitrosulfones (e.g. 2) in high yield. Transformation of the nitro group of the adduct to a keto function (Nef type reaction) and subsequent elimination of benzenesulfinic acid afforded conjugated dienones and dienals with high stereoselectivity.
