219143-49-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 219143-49-4 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, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 219143-49:
(8*2)+(7*1)+(6*9)+(5*1)+(4*4)+(3*3)+(2*4)+(1*9)=124
124 % 10 = 4
So 219143-49-4 is a valid CAS Registry Number.
