Check Digit Verification of cas no

The CAS Registry Mumber 216776-96-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,7,7 and 6 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 216776-96:
(8*2)+(7*1)+(6*6)+(5*7)+(4*7)+(3*6)+(2*9)+(1*6)=164
164 % 10 = 4
So 216776-96-4 is a valid CAS Registry Number.

Chakraborty, Manisha,McConville, David B.,Saito, Takeshi,Meng, Huihan,Rinaldi, Peter L.,Tessier, Claire A.,Youngs, Wiley J.

, p. 8237 - 8240 (1998)

A new palladium-copper catalyzed intramolecular acetylene-zipper type bicyclization between alkyne and hydroxy functionality of an alkynyl hydroquinone has been observed to give a highly conjugated ring system.
