136093-04-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136093-04-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,0,9 and 3 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 136093-04:
(8*1)+(7*3)+(6*6)+(5*0)+(4*9)+(3*3)+(2*0)+(1*4)=114
114 % 10 = 4
So 136093-04-4 is a valid CAS Registry Number.

Synthesis of β-hydroxy-α-amino acids by aldol condensation using a chiral phase transfer catalyst
Gasparski,Miller
, p. 5367 - 5378 (1991)
Efficient, nearly racemic syntheses of β-hydroxy-α-amino acids by aldol condensations between t-butyl (diphenylmethylene)glycinate 2 and aldehydes under phase transfer catalytic conditions in the presence of the chiral catalyst N-benzylcinchoninium chloride are described.
