1293917-93-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1293917-93-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,3,9,1 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1293917-93:
(9*1)+(8*2)+(7*9)+(6*3)+(5*9)+(4*1)+(3*7)+(2*9)+(1*3)=197
197 % 10 = 7
So 1293917-93-7 is a valid CAS Registry Number.

Hetero Diels-Alder reactions of acyl phosphonates: Synthesis of glycosyl type phosphonates
Polat-Cakir, Sidika,Demir, Ayhan S.
, p. 2396 - 2401 (2011/04/26)
We have prepared glycosyl type phosphonates via hetero Diels-Alder (HDA) reactions of acyl phosphonates with electron rich dienes. HDA reactions of acyl phosphonates with Danishefsky's diene required thermal activation to yield the desired dihydropyranone
