1420333-47-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1420333-47-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,0,3,3 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1420333-47:
(9*1)+(8*4)+(7*2)+(6*0)+(5*3)+(4*3)+(3*3)+(2*4)+(1*7)=106
106 % 10 = 6
So 1420333-47-6 is a valid CAS Registry Number.
