Check Digit Verification of cas no

The CAS Registry Mumber 851912-49-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,1,9,1 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 851912-49:
(8*8)+(7*5)+(6*1)+(5*9)+(4*1)+(3*2)+(2*4)+(1*9)=177
177 % 10 = 7
So 851912-49-7 is a valid CAS Registry Number.
