Check Digit Verification of cas no

The CAS Registry Mumber 190712-20-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,7,1 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 190712-20:
(8*1)+(7*9)+(6*0)+(5*7)+(4*1)+(3*2)+(2*2)+(1*0)=120
120 % 10 = 0
So 190712-20-0 is a valid CAS Registry Number.
