Check Digit Verification of cas no
The CAS Registry Mumber 20038-95-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,0,3 and 8 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 20038-95:
(7*2)+(6*0)+(5*0)+(4*3)+(3*8)+(2*9)+(1*5)=73
73 % 10 = 3
So 20038-95-3 is a valid CAS Registry Number.
