Check Digit Verification of cas no
The CAS Registry Mumber 42003-88-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,0,0 and 3 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 42003-88:
(7*4)+(6*2)+(5*0)+(4*0)+(3*3)+(2*8)+(1*8)=73
73 % 10 = 3
So 42003-88-3 is a valid CAS Registry Number.
