Check Digit Verification of cas no

The CAS Registry Mumber 1321621-41-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,1,6,2 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1321621-41:
(9*1)+(8*3)+(7*2)+(6*1)+(5*6)+(4*2)+(3*1)+(2*4)+(1*1)=103
103 % 10 = 3
So 1321621-41-3 is a valid CAS Registry Number.
