Check Digit Verification of cas no

The CAS Registry Mumber 129138-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,3 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 129138-22:
(8*1)+(7*2)+(6*9)+(5*1)+(4*3)+(3*8)+(2*2)+(1*2)=123
123 % 10 = 3
So 129138-22-3 is a valid CAS Registry Number.

A Single-Crystal X-Ray Analysis of a Novel Intramolecular Hydrogen-Bonded Biphenyl Phosphorane

Abell, Andrew D.,Morris, Kathryn B.,McKee, Vickie

, p. 765 - 771 (2007/10/02)

An X-ray crystal structure and 1H n.m.r. analysis of the biphenyl phosphorane (4a) has revealed the presence of an intramolecular hydrogen bond resulting in an unusual biphenyl with a bridge forming a nine-membered ring.The related biphenyl phosphorane (4
