219143-55-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 219143-55-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,1,4 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 219143-55:
(8*2)+(7*1)+(6*9)+(5*1)+(4*4)+(3*3)+(2*5)+(1*5)=122
122 % 10 = 2
So 219143-55-2 is a valid CAS Registry Number.
