Check Digit Verification of cas no

The CAS Registry Mumber 157022-93-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,0,2 and 2 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 157022-93:
(8*1)+(7*5)+(6*7)+(5*0)+(4*2)+(3*2)+(2*9)+(1*3)=120
120 % 10 = 0
So 157022-93-0 is a valid CAS Registry Number.
