31374-61-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 31374-61-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,3,7 and 4 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 31374-61:
(7*3)+(6*1)+(5*3)+(4*7)+(3*4)+(2*6)+(1*1)=95
95 % 10 = 5
So 31374-61-5 is a valid CAS Registry Number.
