Check Digit Verification of cas no
The CAS Registry Mumber 20503-40-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,0 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20503-40:
(7*2)+(6*0)+(5*5)+(4*0)+(3*3)+(2*4)+(1*0)=56
56 % 10 = 6
So 20503-40-6 is a valid CAS Registry Number.
