Check Digit Verification of cas no
The CAS Registry Mumber 6486-55-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,8 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 6486-55:
(6*6)+(5*4)+(4*8)+(3*6)+(2*5)+(1*5)=121
121 % 10 = 1
So 6486-55-1 is a valid CAS Registry Number.
