223419-42-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 223419-42-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,4,1 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 223419-42:
(8*2)+(7*2)+(6*3)+(5*4)+(4*1)+(3*9)+(2*4)+(1*2)=109
109 % 10 = 9
So 223419-42-9 is a valid CAS Registry Number.
