Check Digit Verification of cas no

The CAS Registry Mumber 690638-62-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,0,6,3 and 8 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 690638-62:
(8*6)+(7*9)+(6*0)+(5*6)+(4*3)+(3*8)+(2*6)+(1*2)=191
191 % 10 = 1
So 690638-62-1 is a valid CAS Registry Number.

Hydrotelluration and carbotelluration of acetylenic sulfoxides: Regio- and stereoselective preparation of α- and β-organotellurovinyl sulfoxides

Xu, Qing,Huang, Xian,Ni, Jun

, p. 2981 - 2984 (2004)

(Z)-β-Organotellurovinyl sulfoxides were synthesized via a highly regio- and stereoselective anti-hydrotelluration of acetylenic sulfoxides. α-Organotellurovinyl sulfoxides were obtained from a three component syn-carbotelluration reaction of acetylenic s
