Check Digit Verification of cas no

The CAS Registry Mumber 63234-26-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,2,3 and 4 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 63234-26:
(7*6)+(6*3)+(5*2)+(4*3)+(3*4)+(2*2)+(1*6)=104
104 % 10 = 4
So 63234-26-4 is a valid CAS Registry Number.
