Check Digit Verification of cas no

The CAS Registry Mumber 672883-23-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,2,8,8 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 672883-23:
(8*6)+(7*7)+(6*2)+(5*8)+(4*8)+(3*3)+(2*2)+(1*3)=197
197 % 10 = 7
So 672883-23-7 is a valid CAS Registry Number.
