409305-55-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 409305-55-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,9,3,0 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 409305-55:
(8*4)+(7*0)+(6*9)+(5*3)+(4*0)+(3*5)+(2*5)+(1*5)=131
131 % 10 = 1
So 409305-55-1 is a valid CAS Registry Number.

Tin powder-promoted diastereoselective allylation of chiral acylhydrazones

Peng, Xiansha,Wang, Ke-Hu,Huang, Danfeng,Wang, Juanjuan,Wang, Yalin,Su, Yingpeng,Hu, Yulai,Fu, Ying

, (2017/09/26)

An efficient method for the allylation of chiral acylhydrazones derived from aldehydes has been developed to give the corresponding allylic hydrazides in good yields and diastereoselectivities. The method uses a combination of tin powder and allylic bromide as allylation system, which avoids the use of toxic allylic stannanes while retaining their merits.

Asymmetric allylsilane additions to enantiopure N-acylhydrazones with dual activation by fluoride and In(OTF)3

Friestad,Ding

, p. 4491 - 4493 (2007/10/03)

A mild, convenient, and stereoselective addition of allylsilanes to enantiopure N-acylhydrazones occurs at room temperature upon complementary activation of both the allylsilane and the hydrazone (see scheme; OTf = trifluoromethanesulfonate). The reaction
