153391-18-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 153391-18-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,3,9 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 153391-18:
(8*1)+(7*5)+(6*3)+(5*3)+(4*9)+(3*1)+(2*1)+(1*8)=125
125 % 10 = 5
So 153391-18-5 is a valid CAS Registry Number.

Asymmetric 1,3-dipolar cycloaddition of nitrile oxides to new chiral acrylamides derived from (S)-indoline-2-carboxylic acid
Kim,Kim,Park
, p. 6063 - 6066 (1993)
Asymmetric 1,3-dipolar cycloaddition of nitrile oxides to new chiral acrylamides (3a-c) is reported to give the chiral Δ2-isoxazolines with the high diastereoselectivity (up to 95:5).
