Check Digit Verification of cas no

The CAS Registry Mumber 136886-86-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,8,8 and 6 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 136886-86:
(8*1)+(7*3)+(6*6)+(5*8)+(4*8)+(3*6)+(2*8)+(1*6)=177
177 % 10 = 7
So 136886-86-7 is a valid CAS Registry Number.
