219140-84-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 219140-84-8 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 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 219140-84:
(8*2)+(7*1)+(6*9)+(5*1)+(4*4)+(3*0)+(2*8)+(1*4)=118
118 % 10 = 8
So 219140-84-8 is a valid CAS Registry Number.
