Check Digit Verification of cas no

The CAS Registry Mumber 158147-91-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,1,4 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 158147-91:
(8*1)+(7*5)+(6*8)+(5*1)+(4*4)+(3*7)+(2*9)+(1*1)=152
152 % 10 = 2
So 158147-91-2 is a valid CAS Registry Number.
