Check Digit Verification of cas no
The CAS Registry Mumber 63261-18-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,2,6 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 63261-18:
(7*6)+(6*3)+(5*2)+(4*6)+(3*1)+(2*1)+(1*8)=107
107 % 10 = 7
So 63261-18-7 is a valid CAS Registry Number.
