57716-69-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57716-69-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,7,1 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 57716-69:
(7*5)+(6*7)+(5*7)+(4*1)+(3*6)+(2*6)+(1*9)=155
155 % 10 = 5
So 57716-69-5 is a valid CAS Registry Number.
