Check Digit Verification of cas no
The CAS Registry Mumber 54815-41-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,8,1 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 54815-41:
(7*5)+(6*4)+(5*8)+(4*1)+(3*5)+(2*4)+(1*1)=127
127 % 10 = 7
So 54815-41-7 is a valid CAS Registry Number.
