Check Digit Verification of cas no

The CAS Registry Mumber 151126-94-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,1,2 and 6 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 151126-94:
(8*1)+(7*5)+(6*1)+(5*1)+(4*2)+(3*6)+(2*9)+(1*4)=102
102 % 10 = 2
So 151126-94-2 is a valid CAS Registry Number.
