Check Digit Verification of cas no
The CAS Registry Mumber 40673-25-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,6,7 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 40673-25:
(7*4)+(6*0)+(5*6)+(4*7)+(3*3)+(2*2)+(1*5)=104
104 % 10 = 4
So 40673-25-4 is a valid CAS Registry Number.
