Check Digit Verification of cas no
The CAS Registry Mumber 33142-24-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,1,4 and 2 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 33142-24:
(7*3)+(6*3)+(5*1)+(4*4)+(3*2)+(2*2)+(1*4)=74
74 % 10 = 4
So 33142-24-4 is a valid CAS Registry Number.
