1420198-86-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1420198-86-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,0,1,9 and 8 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1420198-86:
(9*1)+(8*4)+(7*2)+(6*0)+(5*1)+(4*9)+(3*8)+(2*8)+(1*6)=142
142 % 10 = 2
So 1420198-86-2 is a valid CAS Registry Number.
