146860-52-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 146860-52-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,8,6 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 146860-52:
(8*1)+(7*4)+(6*6)+(5*8)+(4*6)+(3*0)+(2*5)+(1*2)=148
148 % 10 = 8
So 146860-52-8 is a valid CAS Registry Number.

Concave Reagents. 12. Polymerfixation of Concave Pyridines

Luening, Ulrich,Gerst, Matthias

, p. 656 - 660 (1992)

Via a metal ion template directed synthesis and a high dilution cyclization, a bimacrocyclic 4-benzyloxyethoxy-substituted concave pyridine 8 was synthesized from dialdehyde 3, diamine 4 and diacyl dichloride 7 in 54percent overall yield.Pd-catalyzed hydrogenolysis of 8 afforded the OH-substituted concave pyridine 9 which could be attached to a Merrifield resin 10 after deprotonation with NaH.The modified polymer 11 contained 10percent (w/w) of 8.
