1420904-71-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1420904-71-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,0,9,0 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1420904-71:
(9*1)+(8*4)+(7*2)+(6*0)+(5*9)+(4*0)+(3*4)+(2*7)+(1*1)=127
127 % 10 = 7
So 1420904-71-7 is a valid CAS Registry Number.
