Check Digit Verification of cas no

The CAS Registry Mumber 158694-45-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,6,9 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 158694-45:
(8*1)+(7*5)+(6*8)+(5*6)+(4*9)+(3*4)+(2*4)+(1*5)=182
182 % 10 = 2
So 158694-45-2 is a valid CAS Registry Number.
