Check Digit Verification of cas no

The CAS Registry Mumber 1228216-82-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,2,1 and 6 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1228216-82:
(9*1)+(8*2)+(7*2)+(6*8)+(5*2)+(4*1)+(3*6)+(2*8)+(1*2)=137
137 % 10 = 7
So 1228216-82-7 is a valid CAS Registry Number.
