Check Digit Verification of cas no
The CAS Registry Mumber 25551-28-4 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, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 25551-28:
(7*2)+(6*5)+(5*5)+(4*5)+(3*1)+(2*2)+(1*8)=104
104 % 10 = 4
So 25551-28-4 is a valid CAS Registry Number.
