4372-03-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4372-03-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,7 and 2 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4372-03:
(6*4)+(5*3)+(4*7)+(3*2)+(2*0)+(1*3)=76
76 % 10 = 6
So 4372-03-6 is a valid CAS Registry Number.
