94112-85-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 94112-85-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,1,1 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 94112-85:
(7*9)+(6*4)+(5*1)+(4*1)+(3*2)+(2*8)+(1*5)=123
123 % 10 = 3
So 94112-85-3 is a valid CAS Registry Number.

Structure Elucidation and Total Synthesis of New Tanshinones Isolated from Salvia miltiorrhiza Bunge (Danshen)

Chang, Hson Mou,Cheng, Kwok Ping,Choang, Tai Francis,Chow, Hak Fun,Chui, Kuk Ying,et al.

, p. 3537 - 3543 (1990)

Totally 11 new compounds have been isolated from the dried root of Salvia miltiorrhiza Bunge "Danshen" and their structures were elucidated by means of spectrometric methods.The total syntheses of two new compounds, namely, 1,2-didehydromiltirone and 4-methylenemiltirone, are also reported.

A novel type of retinoic acid receptor antagonist: Synthesis and structure-activity relationships of heterocyclic ring-containing benzoic acid derivatives

Yoshimura,Nagai,Hibi,Kikuchi,Abe,Hida,Higashi,Yamanaka

, p. 3163 - 3173 (2007/10/02)

A new series of heterocyclic ring-containing benzoic acids was prepared, and the binding affinity and antagonism of its members against all-trans- retinoic acid were evaluated by in vitro assay systems using human promyelocytic leukemia (HL-60) cells. Structure-activity relationships indicated that both an N-substituted pyrrole or pyrazole (1-position) and a hydrophobic region, with these linked by a ring system, were indispensable for effective antagonism. Among the compounds evaluated, optimal antagonism was exhibited by 4-[4,5,7,8,9,10-hexahydro-7,7,10,-10-tetramethyl-1-(3- pyridylmethyl)anthra[1,2-b]pyrrol-3-yl]benzoic acid (31), 4-[4,5,7,8,9,10- hexahydro-7,7,10,10-tetramethyl-1-(3-pyridylmethyl)-5-thiaanthra[1,2- b]pyrrol-3-yl]benzoic acid (40), and 4-[4,5,7,8,9,10-hexahydro-7,7,10,10- tetramethyl-1-(3-pyridylmethyl)anthra[2,1-d]pyrazol-3-yl]benzoic acid (55), all of which possess a 3-pyridylmethyl group at the five-membered ring nitrogen atom.
