4283-57-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4283-57-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,8 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.Calculate Digit Verification of CAS Registry Number 4283-57:
(6*4)+(5*2)+(4*8)+(3*3)+(2*5)+(1*7)=92
92 % 10 = 2
So 4283-57-2 is a valid CAS Registry Number.
