Check Digit Verification of cas no

The CAS Registry Mumber 156832-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,8,3 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 156832-22:
(8*1)+(7*5)+(6*6)+(5*8)+(4*3)+(3*2)+(2*2)+(1*2)=143
143 % 10 = 3
So 156832-22-3 is a valid CAS Registry Number.
