Check Digit Verification of cas no
The CAS Registry Mumber 25551-59-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,5,5 and 1 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 25551-59:
(7*2)+(6*5)+(5*5)+(4*5)+(3*1)+(2*5)+(1*9)=111
111 % 10 = 1
So 25551-59-1 is a valid CAS Registry Number.
