Check Digit Verification of cas no

The CAS Registry Mumber 887769-17-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,7,7,6 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 887769-17:
(8*8)+(7*8)+(6*7)+(5*7)+(4*6)+(3*9)+(2*1)+(1*7)=257
257 % 10 = 7
So 887769-17-7 is a valid CAS Registry Number.
