1416721-04-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1416721-04-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,6,7,2 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1416721-04:
(9*1)+(8*4)+(7*1)+(6*6)+(5*7)+(4*2)+(3*1)+(2*0)+(1*4)=134
134 % 10 = 4
So 1416721-04-4 is a valid CAS Registry Number.

Synthesis and reduction of new sulfinimines with isobornane structure
Izmest'Ev,Sudarikov,Rubtsova,Slepukhin,Kuchin
, p. 1407 - 1418 (2013/05/22)
Synthesis of sulfenimines proceeding from isobornanethiol with yields up to 78% was performed. They were oxidized to diastereomeric isobornylsulfinimines and the latter were reduced to N-substituted isobornylsulfinamides in high yields.
