7740-56-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7740-56-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,4 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.Calculate Digit Verification of CAS Registry Number 7740-56:
(6*7)+(5*7)+(4*4)+(3*0)+(2*5)+(1*6)=109
109 % 10 = 9
So 7740-56-9 is a valid CAS Registry Number.
