68003-68-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 68003-68-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,0,0 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 68003-68:
(7*6)+(6*8)+(5*0)+(4*0)+(3*3)+(2*6)+(1*8)=119
119 % 10 = 9
So 68003-68-9 is a valid CAS Registry Number.

, p. 7100 - 7102 (2007/10/03)
N-(Alkylidene or 1-arylmethylidene)-2-propenylamines were regiospecifically functionalized to novel N-(alkylidene or 1-arylmethylidene)-3-bromo-2- fluoropropylamines, which were proven to be excellent precursors for 3-fluoroazetidines.
