Check Digit Verification of cas no
The CAS Registry Mumber 25359-91-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,3,5 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 25359-91:
(7*2)+(6*5)+(5*3)+(4*5)+(3*9)+(2*9)+(1*1)=125
125 % 10 = 5
So 25359-91-5 is a valid CAS Registry Number.
