Check Digit Verification of cas no
The CAS Registry Mumber 25023-01-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,0,2 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 25023-01:
(7*2)+(6*5)+(5*0)+(4*2)+(3*3)+(2*0)+(1*1)=62
62 % 10 = 2
So 25023-01-2 is a valid CAS Registry Number.
