Check Digit Verification of cas no

The CAS Registry Mumber 138509-01-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,5,0 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 138509-01:
(8*1)+(7*3)+(6*8)+(5*5)+(4*0)+(3*9)+(2*0)+(1*1)=130
130 % 10 = 0
So 138509-01-0 is a valid CAS Registry Number.

SYNTHESIS OF NEW OPTICALLY ACTIVE CYANOCYCLOPROPANES AS CHIRAL DOPANTS FOR FERROELECTRIC LIQUID CRYSTALS

Kusumoto, Tetsuo,Nakayama, Akiko,Sato, Ken-ichi,Hiyama, Tamejiro,Takehara, Sadao,et al.

, p. 939 - 942 (2007/10/02)

Optically active 2-alkyl-1-aryl-cyanocyclopropanes were synthesized from 2-aryl-4-hydroxyalkanenitriles which in turn were obtained by the reaction of chiral 1,2-epoxyalkanes with the carbanions derived from arylacetonitriles.
