Check Digit Verification of cas no

The CAS Registry Mumber 1372972-21-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,2,9,7 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1372972-21:
(9*1)+(8*3)+(7*7)+(6*2)+(5*9)+(4*7)+(3*2)+(2*2)+(1*1)=178
178 % 10 = 8
So 1372972-21-8 is a valid CAS Registry Number.
