Check Digit Verification of cas no

The CAS Registry Mumber 130521-20-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,5,2 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 130521-20:
(8*1)+(7*3)+(6*0)+(5*5)+(4*2)+(3*1)+(2*2)+(1*0)=69
69 % 10 = 9
So 130521-20-9 is a valid CAS Registry Number.

Figure Presented. A series of novel 2-arylbenzoxazoles that upregulate the production of utrophin in murine H2K cells, as assessed using a luciferase reporter linked assay, have been identified. This compound class appears to hold considerable promise as a potential treatment for Duchenne muscular dystrophy. Following the delineation of structure-activity relationships in the series, a number of potent upregulators were identified, and preliminary ADME evaluation is described. These studies have resulted in the identification of 1, a compound that has been progressed to clinical trials.

Unequivocal Preparation of 4- and 5-Acyl-2-aminophenols

Aichaoui, Hocine,Lesieur, Isabelle,Henichart, Jean-Pierre

, p. 679 - 680 (2007/10/02)

Unequivocal methods for the specific preparation of 4- or 5-acyl-2-aminophenols are reported. 5-Acyl-2-aminophenols are obtained by ring opening with dilute sodium hydroxide of 2(3H)-benzoxazolinones acylated at position 6. 4-Acyl-2-aminophenols are obtai
