4992-22-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4992-22-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,9 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.Calculate Digit Verification of CAS Registry Number 4992-22:
(6*4)+(5*9)+(4*9)+(3*2)+(2*2)+(1*2)=117
117 % 10 = 7
So 4992-22-7 is a valid CAS Registry Number.
