Check Digit Verification of cas no

The CAS Registry Mumber 4919-64-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,1 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4919-64:
(6*4)+(5*9)+(4*1)+(3*9)+(2*6)+(1*4)=116
116 % 10 = 6
So 4919-64-6 is a valid CAS Registry Number.
