5776-56-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5776-56-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,7 and 6 respectively; the second part has 2 digits, 5 and 6 respectively.Calculate Digit Verification of CAS Registry Number 5776-56:
(6*5)+(5*7)+(4*7)+(3*6)+(2*5)+(1*6)=127
127 % 10 = 7
So 5776-56-7 is a valid CAS Registry Number.
