Check Digit Verification of cas no

The CAS Registry Mumber 857732-20-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,7,3 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 857732-20:
(8*8)+(7*5)+(6*7)+(5*7)+(4*3)+(3*2)+(2*2)+(1*0)=198
198 % 10 = 8
So 857732-20-8 is a valid CAS Registry Number.

Fourier transform infrared isotopic study of the C12 chain trapped in solid Ar

Ding,Wang,Rittby,Graham

, p. 5113 - 5120 (2000)

A Fourier transform infrared investigation of the 13C isotopic spectrum of linear C12 in solid Ar coupled with density functional theory calculations at the B3LYP/cc-pVDZ level has resulted in the identification of the v8= 1997.2 and v9 = 1818.0 cm-1 stretching modes. Agreement between experimental measurements and theory is very good. The identification of a third mode v7 =2140.6 cm-1 is considered tentative.
