Check Digit Verification of cas no

The CAS Registry Mumber 4641-78-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,4 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4641-78:
(6*4)+(5*6)+(4*4)+(3*1)+(2*7)+(1*8)=95
95 % 10 = 5
So 4641-78-5 is a valid CAS Registry Number.
