Check Digit Verification of cas no

The CAS Registry Mumber 1202014-20-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,2,0,1 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1202014-20:
(9*1)+(8*2)+(7*0)+(6*2)+(5*0)+(4*1)+(3*4)+(2*2)+(1*0)=57
57 % 10 = 7
So 1202014-20-7 is a valid CAS Registry Number.
