749253-90-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 749253-90-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,9,2,5 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 749253-90:
(8*7)+(7*4)+(6*9)+(5*2)+(4*5)+(3*3)+(2*9)+(1*0)=195
195 % 10 = 5
So 749253-90-5 is a valid CAS Registry Number.

Asymmetric synthesis of syn-(2R,3S)-and anti-(2S,3S)-ethyl diamino-3-phenylpropanoates from N-(benzylidene)-p-toluenesulfinamide and glycine enolates
Davis, Franklin A.,Deng, Jianghe
, p. 2789 - 2792 (2007/10/03)
Addition of differentially N-protected glycine enolates to enantiopure sulfinimines affords syn- and anti-α,β-diamino esters with high diastereoselectivities and good yields.
