76571-57-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76571-57-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,5,7 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 76571-57:
(7*7)+(6*6)+(5*5)+(4*7)+(3*1)+(2*5)+(1*7)=158
158 % 10 = 8
So 76571-57-8 is a valid CAS Registry Number.
