2294-77-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2294-77-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,9 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.Calculate Digit Verification of CAS Registry Number 2294-77:
(6*2)+(5*2)+(4*9)+(3*4)+(2*7)+(1*7)=91
91 % 10 = 1
So 2294-77-1 is a valid CAS Registry Number.
