1273545-99-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1273545-99-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,3,5,4 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1273545-99:
(9*1)+(8*2)+(7*7)+(6*3)+(5*5)+(4*4)+(3*5)+(2*9)+(1*9)=175
175 % 10 = 5
So 1273545-99-5 is a valid CAS Registry Number.

Ammonium ylides for the diastereoselective synthesis of glycidic amides
Waser, Mario,Herchl, Richard,Mueller, Norbert
, p. 2170 - 2172 (2011)
A highly trans-selective protocol for the synthesis of glycidic amides was developed. This approach gave access to oxiranes by reacting stabilised ammonium ylides bearing an α-carbonyl group and aromatic aldehydes in moderate to good yields.
