Check Digit Verification of cas no

The CAS Registry Mumber 66967-83-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,9,6 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 66967-83:
(7*6)+(6*6)+(5*9)+(4*6)+(3*7)+(2*8)+(1*3)=187
187 % 10 = 7
So 66967-83-7 is a valid CAS Registry Number.
