Check Digit Verification of cas no
The CAS Registry Mumber 4003-36-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,0 and 3 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4003-36:
(6*4)+(5*0)+(4*0)+(3*3)+(2*3)+(1*6)=45
45 % 10 = 5
So 4003-36-5 is a valid CAS Registry Number.
