Check Digit Verification of cas no

The CAS Registry Mumber 1557154-83-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,5,7,1,5 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1557154-83:
(9*1)+(8*5)+(7*5)+(6*7)+(5*1)+(4*5)+(3*4)+(2*8)+(1*3)=182
182 % 10 = 2
So 1557154-83-2 is a valid CAS Registry Number.
