Check Digit Verification of cas no
The CAS Registry Mumber 1325-93-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,2 and 5 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1325-93:
(6*1)+(5*3)+(4*2)+(3*5)+(2*9)+(1*3)=65
65 % 10 = 5
So 1325-93-5 is a valid CAS Registry Number.
