1226792-86-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1226792-86-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,6,7,9 and 2 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1226792-86:
(9*1)+(8*2)+(7*2)+(6*6)+(5*7)+(4*9)+(3*2)+(2*8)+(1*6)=174
174 % 10 = 4
So 1226792-86-4 is a valid CAS Registry Number.

Selective approach toward multifunctionalized lactams by lewis acid promoted PhSe group transfer radical cyclization

Yu, Jin-Di,Ding, Wei,Lian, Gao-Yan,Song, Ke-Sheng,Zhang, Dan-Wei,Gao, Xiang,Yang, Dan

supporting information; experimental part, p. 3232 - 3239 (2010/08/19)

We have developed a regiospecific and highly stereoselective strategy for constructing the five-/six-membered monocyclic and bicyclic nitrogen heterocycle skeletons using PhSe group transfer radical cyclization of α-phenylseleno amido esters promoted by a Lewis acid (e.g., Yb(OTf)3) under UV irradiation. We obtained 5-/6-exo-trig mode cyclization products for the N-allyl/homoallyl substrates, whereas the enamide substrate gave 5-endo-trig ring closure.
