Check Digit Verification of cas no

The CAS Registry Mumber 959965-28-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,9,9,6 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 959965-28:
(8*9)+(7*5)+(6*9)+(5*9)+(4*6)+(3*5)+(2*2)+(1*8)=257
257 % 10 = 7
So 959965-28-7 is a valid CAS Registry Number.
