52312-01-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 52312-01-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,3,1 and 2 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 52312-01:
(7*5)+(6*2)+(5*3)+(4*1)+(3*2)+(2*0)+(1*1)=73
73 % 10 = 3
So 52312-01-3 is a valid CAS Registry Number.
