Check Digit Verification of cas no

The CAS Registry Mumber 1265902-70-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,5,9,0 and 2 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1265902-70:
(9*1)+(8*2)+(7*6)+(6*5)+(5*9)+(4*0)+(3*2)+(2*7)+(1*0)=162
162 % 10 = 2
So 1265902-70-2 is a valid CAS Registry Number.

Toward the second generation synthesis of aplyronine A: Stereocontrolled assembly of the C1-C19 segment by using an asymmetric Nozaki-Hiyama-Kishi coupling

Kobayashi, Kenichi,Fujii, Yusuke,Hayakawa, Ichiro,Kigoshi, Hideo

supporting information; experimental part, p. 900 - 903 (2011/05/03)

An efficient synthesis of the C1-C19 segment of aplyronine A is described. Stereoselective construction of the C14-C15 (E)-trisubstituted double bond and the C13 stereocenter was achieved by using an asymmetric Nozaki-Hiyama-Kishi coupling.(Figure Presented)
