Check Digit Verification of cas no
The CAS Registry Mumber 1324-33-0 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 4 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1324-33:
(6*1)+(5*3)+(4*2)+(3*4)+(2*3)+(1*3)=50
50 % 10 = 0
So 1324-33-0 is a valid CAS Registry Number.
