740815-77-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 740815-77-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,0,8,1 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 740815-77:
(8*7)+(7*4)+(6*0)+(5*8)+(4*1)+(3*5)+(2*7)+(1*7)=164
164 % 10 = 4
So 740815-77-4 is a valid CAS Registry Number.

Enantioselective Diels-Alder reactions of 3-(acyloxy)acrylates
Sibi, Mukund P.,Matsunaga, Hirofumi
, p. 5925 - 5929 (2007/10/03)
Diels-Alder reactions with 3-(acyloxy)acrylates using chiral Lewis acid catalysts have been successfully carried out. These reactions proceed with high enantioselectivity when a chiral Lewis acid derived from Cu(OTf)2 and a bisoxazoline is used
