Check Digit Verification of cas no
The CAS Registry Mumber 31457-83-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,4,5 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 31457-83:
(7*3)+(6*1)+(5*4)+(4*5)+(3*7)+(2*8)+(1*3)=107
107 % 10 = 7
So 31457-83-7 is a valid CAS Registry Number.
