Check Digit Verification of cas no

The CAS Registry Mumber 139680-96-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,8 and 0 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 139680-96:
(8*1)+(7*3)+(6*9)+(5*6)+(4*8)+(3*0)+(2*9)+(1*6)=169
169 % 10 = 9
So 139680-96-9 is a valid CAS Registry Number.

Ruthenium Complex-catalyzed Selective Syntheses of 3,5-Dienoic Acid Derivatives by Coupling of 1,3-Dienes or Allylic Carbonates with Acrylic Compounds

Mitsudo, Take-aki,Zhang, Shi-Wei,Kondo, Teruyuki,Watanabe, Yoshihisa

, p. 341 - 344 (1992)

Ru(cod)(cot) catalyzes highly selective codimerization of 1,3-dienes with acrylic compounds and first linear coupling reaction of allylic carbonates with the acrylic amide to give 3,5-dienoic acid derivatives; cod = cycloocta-1,5-diene; cot = cycloocta-1,
