56581-76-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 56581-76-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,5,8 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 56581-76:
(7*5)+(6*6)+(5*5)+(4*8)+(3*1)+(2*7)+(1*6)=151
151 % 10 = 1
So 56581-76-1 is a valid CAS Registry Number.
