75426-57-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75426-57-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,4,2 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 75426-57:
(7*7)+(6*5)+(5*4)+(4*2)+(3*6)+(2*5)+(1*7)=142
142 % 10 = 2
So 75426-57-2 is a valid CAS Registry Number.
