31201-88-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 31201-88-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,2,0 and 1 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 31201-88:
(7*3)+(6*1)+(5*2)+(4*0)+(3*1)+(2*8)+(1*8)=64
64 % 10 = 4
So 31201-88-4 is a valid CAS Registry Number.
