Check Digit Verification of cas no
The CAS Registry Mumber 1033-90-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,3 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1033-90:
(6*1)+(5*0)+(4*3)+(3*3)+(2*9)+(1*0)=45
45 % 10 = 5
So 1033-90-5 is a valid CAS Registry Number.
