4224-37-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4224-37-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,2 and 4 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4224-37:
(6*4)+(5*2)+(4*2)+(3*4)+(2*3)+(1*7)=67
67 % 10 = 7
So 4224-37-7 is a valid CAS Registry Number.
