156904-85-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 156904-85-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,9,0 and 4 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 156904-85:
(8*1)+(7*5)+(6*6)+(5*9)+(4*0)+(3*4)+(2*8)+(1*5)=157
157 % 10 = 7
So 156904-85-7 is a valid CAS Registry Number.

3-Di-[(S)-2-acetoxypropanoyl] aminoquinazolin-4(3H)-ones: Stereostructure and application in kinetic resolution of amines

Al-Sehemi, Abdullah G.,Atkinson, Robert S.,Fawcett, John,Russell, David R.

, p. 2243 - 2246 (2000)

Whereas 3-diacylaminoquinazolin-4(3H)-ones (DAQs) have been previously shown to undergo rapid exo/endo-endo/exo conformational interconversion of their imide carbonyl groups, the title DAQs are believed to exist in one single exo/endo form and consequently their N-N bonds are chiral axis: one of these DAQs, substituted with a diphenylmethyl group on the Q-2 position, reacts preferentially with one enantiomer of racemic 2-methyl-piperidine at the 2-acetoxypropanoyl imide carbonyl group (ee 94%).

Atkinson, Robert S.,Barker, Emma,Price, Christopher J.,Russell, David R.

, p. 1159 - 1160 (1994)

Two diastereoisomers of 3-(diacylamino)quinazolinone 5 are separated and identified by crystal structure determinations which confirm the presence of an N-N chiral axis: one diastereoisomer of enantiopure 8 reacts with racemic 1-phenylethylamine exclusive
