Check Digit Verification of cas no

The CAS Registry Mumber 49776-78-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,7,7 and 6 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 49776-78:
(7*4)+(6*9)+(5*7)+(4*7)+(3*6)+(2*7)+(1*8)=185
185 % 10 = 5
So 49776-78-5 is a valid CAS Registry Number.
