4392-57-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4392-57-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,9 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.Calculate Digit Verification of CAS Registry Number 4392-57:
(6*4)+(5*3)+(4*9)+(3*2)+(2*5)+(1*7)=98
98 % 10 = 8
So 4392-57-8 is a valid CAS Registry Number.
