Check Digit Verification of cas no

The CAS Registry Mumber 40663-11-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,6,6 and 3 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 40663-11:
(7*4)+(6*0)+(5*6)+(4*6)+(3*3)+(2*1)+(1*1)=94
94 % 10 = 4
So 40663-11-4 is a valid CAS Registry Number.
