Check Digit Verification of cas no
The CAS Registry Mumber 4888-55-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,8 and 8 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4888-55:
(6*4)+(5*8)+(4*8)+(3*8)+(2*5)+(1*5)=135
135 % 10 = 5
So 4888-55-5 is a valid CAS Registry Number.
