Check Digit Verification of cas no

The CAS Registry Mumber 661492-83-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,1,4,9 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 661492-83:
(8*6)+(7*6)+(6*1)+(5*4)+(4*9)+(3*2)+(2*8)+(1*3)=177
177 % 10 = 7
So 661492-83-7 is a valid CAS Registry Number.
