1352123-19-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1352123-19-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,2,1,2 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1352123-19:
(9*1)+(8*3)+(7*5)+(6*2)+(5*1)+(4*2)+(3*3)+(2*1)+(1*9)=113
113 % 10 = 3
So 1352123-19-3 is a valid CAS Registry Number.

Procyanidin oligomers. A new method for 4→8 interflavan bond formation using C8-boronic acids and iterative oligomer synthesis through a boron-protection strategy

Dennis, Eric G.,Jeffery, David W.,Johnston, Martin R.,Perkins, Michael V.,Smith, Paul A.

, p. 340 - 348 (2012/01/06)

Interest in the synthesis of procyanidin (catechin or epicatechin) oligomers that contain the 4→8 interflavan linkage remains high, principally due to research into their health effects. A novel coupling utilising a C8-boronic acid as a directing group was developed in the synthesis of natural procyanidin B3 (i.e., 3,4-trans-(+)-catechin-4α→8-(+)- catechin dimer). The key interflavan bond was forged using a novel Lewis acid-promoted coupling of C4-ether 6 with C8-boronic acid 16 to provide the α-linked dimer with high diastereoselectivity. Through the use of a boron protecting group, the new coupling procedure was extended to the synthesis of a protected procyanidin trimer analogous to natural procyanidin C2.
