Check Digit Verification of cas no

The CAS Registry Mumber 142071-82-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,0,7 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 142071-82:
(8*1)+(7*4)+(6*2)+(5*0)+(4*7)+(3*1)+(2*8)+(1*2)=97
97 % 10 = 7
So 142071-82-7 is a valid CAS Registry Number.
