Check Digit Verification of cas no

The CAS Registry Mumber 1027385-16-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,3,8 and 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1027385-16:
(9*1)+(8*0)+(7*2)+(6*7)+(5*3)+(4*8)+(3*5)+(2*1)+(1*6)=135
135 % 10 = 5
So 1027385-16-5 is a valid CAS Registry Number.

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.
