Check Digit Verification of cas no

The CAS Registry Mumber 1268270-62-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,2,7 and 0 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1268270-62:
(9*1)+(8*2)+(7*6)+(6*8)+(5*2)+(4*7)+(3*0)+(2*6)+(1*2)=167
167 % 10 = 7
So 1268270-62-7 is a valid CAS Registry Number.
