7293-77-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7293-77-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,9 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.Calculate Digit Verification of CAS Registry Number 7293-77:
(6*7)+(5*2)+(4*9)+(3*3)+(2*7)+(1*7)=118
118 % 10 = 8
So 7293-77-8 is a valid CAS Registry Number.
