844437-83-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 844437-83-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,4,4,3 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 844437-83:
(8*8)+(7*4)+(6*4)+(5*4)+(4*3)+(3*7)+(2*8)+(1*3)=188
188 % 10 = 8
So 844437-83-8 is a valid CAS Registry Number.

Hydrogenation condition for sequential processes to (+)-trifluoromethyl monomorine
Kim, Guncheol,Kim, Nakjeong
, p. 423 - 425 (2005)
(+)-Trifluoromethyl monomorine has been synthesized under mild hydrogenation condition by initiating reductive cleavage of the oxazoline ring followed by deprotection and intramolecular reductive amination reaction. The precursors could be prepared concis
