4179-22-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4179-22-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,7 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4179-22:
(6*4)+(5*1)+(4*7)+(3*9)+(2*2)+(1*2)=90
90 % 10 = 0
So 4179-22-0 is a valid CAS Registry Number.
