Check Digit Verification of cas no
The CAS Registry Mumber 59253-21-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,2,5 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 59253-21:
(7*5)+(6*9)+(5*2)+(4*5)+(3*3)+(2*2)+(1*1)=133
133 % 10 = 3
So 59253-21-3 is a valid CAS Registry Number.
