57877-99-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57877-99-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,8,7 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 57877-99:
(7*5)+(6*7)+(5*8)+(4*7)+(3*7)+(2*9)+(1*9)=193
193 % 10 = 3
So 57877-99-3 is a valid CAS Registry Number.
