Check Digit Verification of cas no

The CAS Registry Mumber 4794-41-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,9 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4794-41:
(6*4)+(5*7)+(4*9)+(3*4)+(2*4)+(1*1)=116
116 % 10 = 6
So 4794-41-6 is a valid CAS Registry Number.
