Check Digit Verification of cas no

The CAS Registry Mumber 16867-33-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,6 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 16867-33:
(7*1)+(6*6)+(5*8)+(4*6)+(3*7)+(2*3)+(1*3)=137
137 % 10 = 7
So 16867-33-7 is a valid CAS Registry Number.
