Check Digit Verification of cas no

The CAS Registry Mumber 127832-27-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,8,3 and 2 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 127832-27:
(8*1)+(7*2)+(6*7)+(5*8)+(4*3)+(3*2)+(2*2)+(1*7)=133
133 % 10 = 3
So 127832-27-3 is a valid CAS Registry Number.
