4374-58-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4374-58-7 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 4 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4374-58:
(6*4)+(5*3)+(4*7)+(3*4)+(2*5)+(1*8)=97
97 % 10 = 7
So 4374-58-7 is a valid CAS Registry Number.
