31032-92-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 31032-92-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,0,3 and 2 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 31032-92:
(7*3)+(6*1)+(5*0)+(4*3)+(3*2)+(2*9)+(1*2)=65
65 % 10 = 5
So 31032-92-5 is a valid CAS Registry Number.
