Check Digit Verification of cas no

The CAS Registry Mumber 150890-84-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,0,8,9 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 150890-84:
(8*1)+(7*5)+(6*0)+(5*8)+(4*9)+(3*0)+(2*8)+(1*4)=139
139 % 10 = 9
So 150890-84-9 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.
