Check Digit Verification of cas no

The CAS Registry Mumber 315660-97-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,5,6,6 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 315660-97:
(8*3)+(7*1)+(6*5)+(5*6)+(4*6)+(3*0)+(2*9)+(1*7)=140
140 % 10 = 0
So 315660-97-0 is a valid CAS Registry Number.

Steric size in conformational analysis. Steric compression analyzed by circular dichroism spectroscopy

Boiadjiev,Lightner

, p. 11328 - 11339 (2007/10/03)

The relative steric size of methyl, ethyl, isopropyl, tert-butyl, phenyl, and benzyl groups has been determined from a sensitive tetrapyrrole model and exciton coupling circular dichroism (CD) measurements. Unlike the classical cyclohexane model, from whi
