135038-15-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135038-15-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,0,3 and 8 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 135038-15:
(8*1)+(7*3)+(6*5)+(5*0)+(4*3)+(3*8)+(2*1)+(1*5)=102
102 % 10 = 2
So 135038-15-2 is a valid CAS Registry Number.

An asymmetric synthesis of a 3-hydroxy-β-lactam by keteneimine cycloaddition: Utilization of chiral ketenes from carbohydrates
Borer, Bennett C.,Balogh, Douglas W.
, p. 1039 - 1040 (2007/10/02)
The Staudinger reaction of a chiral carbohydrate-based ketene and an imine proceeds to give, after removal of the sugar, cis-3-hydroxy-β-lactam 7 in moderate yield with good asymmetric induction (70% e.e.).
