Check Digit Verification of cas no
The CAS Registry Mumber 31175-20-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,1,7 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 31175-20:
(7*3)+(6*1)+(5*1)+(4*7)+(3*5)+(2*2)+(1*0)=79
79 % 10 = 9
So 31175-20-9 is a valid CAS Registry Number.
