Check Digit Verification of cas no
The CAS Registry Mumber 2063-40-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,6 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2063-40:
(6*2)+(5*0)+(4*6)+(3*3)+(2*4)+(1*0)=53
53 % 10 = 3
So 2063-40-3 is a valid CAS Registry Number.
