419567-22-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 419567-22-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,1,9,5,6 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 419567-22:
(8*4)+(7*1)+(6*9)+(5*5)+(4*6)+(3*7)+(2*2)+(1*2)=169
169 % 10 = 9
So 419567-22-9 is a valid CAS Registry Number.
