57427-95-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57427-95-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,4,2 and 7 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 57427-95:
(7*5)+(6*7)+(5*4)+(4*2)+(3*7)+(2*9)+(1*5)=149
149 % 10 = 9
So 57427-95-9 is a valid CAS Registry Number.
