Check Digit Verification of cas no

The CAS Registry Mumber 2957-26-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,5 and 7 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2957-26:
(6*2)+(5*9)+(4*5)+(3*7)+(2*2)+(1*6)=108
108 % 10 = 8
So 2957-26-8 is a valid CAS Registry Number.
