Check Digit Verification of cas no

The CAS Registry Mumber 82982-16-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,9,8 and 2 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 82982-16:
(7*8)+(6*2)+(5*9)+(4*8)+(3*2)+(2*1)+(1*6)=159
159 % 10 = 9
So 82982-16-9 is a valid CAS Registry Number.

Inoue, Yoshihisa,Ouchi, Mikio,Nakazato, Toshiyo,Matsuda, Takashi,Hakushi, Tadao

, p. 781 - 784 (2007/10/02)

Stilbenocrown ethers 3a,c and 4a,b were synthesized in a cyclization reaction of benzoin with oligoethylene glycol ditosylates (2a-c) under a phase-transfer condition.Extractions of aqueous alkali picrates (Na+-Cs+) were examined with the distilbenocrown ethers 4a,b, the partially-hydrogenated tetraphenylcrown ethers 6a,b, and the fully-hydrogenated tetracyclohexylcrown ethers 7a,b.
