Check Digit Verification of cas no
The CAS Registry Mumber 98633-54-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,6,3 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 98633-54:
(7*9)+(6*8)+(5*6)+(4*3)+(3*3)+(2*5)+(1*4)=176
176 % 10 = 6
So 98633-54-6 is a valid CAS Registry Number.
