Check Digit Verification of cas no
The CAS Registry Mumber 40828-20-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,8,2 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 40828-20:
(7*4)+(6*0)+(5*8)+(4*2)+(3*8)+(2*2)+(1*0)=104
104 % 10 = 4
So 40828-20-4 is a valid CAS Registry Number.
