Check Digit Verification of cas no

The CAS Registry Mumber 1267983-83-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,7,9,8 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1267983-83:
(9*1)+(8*2)+(7*6)+(6*7)+(5*9)+(4*8)+(3*3)+(2*8)+(1*3)=214
214 % 10 = 4
So 1267983-83-4 is a valid CAS Registry Number.
