7240-57-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7240-57-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,4 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.Calculate Digit Verification of CAS Registry Number 7240-57:
(6*7)+(5*2)+(4*4)+(3*0)+(2*5)+(1*7)=85
85 % 10 = 5
So 7240-57-5 is a valid CAS Registry Number.
