1261280-45-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1261280-45-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,1,2,8 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1261280-45:
(9*1)+(8*2)+(7*6)+(6*1)+(5*2)+(4*8)+(3*0)+(2*4)+(1*5)=128
128 % 10 = 8
So 1261280-45-8 is a valid CAS Registry Number.

Enantioselective Organocatalyzed Bromolactonizations: Applications in Natural Product Synthesis

Aursnes, Marius,Tungen, J?rn E.,Hansen, Trond V.

, p. 8287 - 8295 (2016/09/28)

Asymmetric bromolactonization reactions of δ-unsaturated carboxylic acids have been investigated in the presence of 10 chiral squaramide hydrogen-bonding organocatalysts. The best catalyst enabled the cyclization of several 5-arylhex-5-enoic acids into th

Asymmetric bromolactonization catalyzed by a C3-symmetric chiral trisimidazoline

supporting information; experimental part, p. 9174 - 9177 (2011/02/26)

A productive alliance: In an enantioselective organocatalytic bromolactonization of 5-substituted hex-5-enoic acids (see scheme), it appears that the formation of an ion pair through interaction of the trisimidazoline catalyst 1 with the substrate both cr
