Check Digit Verification of cas no

The CAS Registry Mumber 39012-22-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,0,1 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 39012-22:
(7*3)+(6*9)+(5*0)+(4*1)+(3*2)+(2*2)+(1*2)=91
91 % 10 = 1
So 39012-22-1 is a valid CAS Registry Number.
