Check Digit Verification of cas no
The CAS Registry Mumber 25221-53-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,2,2 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 25221-53:
(7*2)+(6*5)+(5*2)+(4*2)+(3*1)+(2*5)+(1*3)=78
78 % 10 = 8
So 25221-53-8 is a valid CAS Registry Number.
