Check Digit Verification of cas no
The CAS Registry Mumber 10134-33-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,1,3 and 4 respectively; the second part has 2 digits, 3 and 3 respectively.Calculate Digit Verification of CAS Registry Number 10134-33:
(7*1)+(6*0)+(5*1)+(4*3)+(3*4)+(2*3)+(1*3)=45
45 % 10 = 5
So 10134-33-5 is a valid CAS Registry Number.
