Check Digit Verification of cas no

The CAS Registry Mumber 127641-81-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,6,4 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 127641-81:
(8*1)+(7*2)+(6*7)+(5*6)+(4*4)+(3*1)+(2*8)+(1*1)=130
130 % 10 = 0
So 127641-81-0 is a valid CAS Registry Number.
