1420844-72-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1420844-72-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,0,8,4 and 4 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1420844-72:
(9*1)+(8*4)+(7*2)+(6*0)+(5*8)+(4*4)+(3*4)+(2*7)+(1*2)=139
139 % 10 = 9
So 1420844-72-9 is a valid CAS Registry Number.
