31335-68-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 31335-68-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,3,3 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 31335-68:
(7*3)+(6*1)+(5*3)+(4*3)+(3*5)+(2*6)+(1*8)=89
89 % 10 = 9
So 31335-68-9 is a valid CAS Registry Number.
