Check Digit Verification of cas no

The CAS Registry Mumber 491876-03-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,1,8,7 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 491876-03:
(8*4)+(7*9)+(6*1)+(5*8)+(4*7)+(3*6)+(2*0)+(1*3)=190
190 % 10 = 0
So 491876-03-0 is a valid CAS Registry Number.

Convenient Approach to 3,4-Diarylisoxazoles Based on the Suzuki Cross-Coupling Reaction

Dileep Kumar,Ho, ManKit M.,Leung, Jennifer M.,Toyokuni, Tatsushi

, p. 1146 - 1151 (2007/10/03)

The Suzuki cross-coupling reaction was found effective for rapid access to a series of 3,4-diarylisoxazoles of pharmacological interest. The efficiency of this approach was demonstrated by the synthesis of the highly potent COX-2-selective inhibitor, 4-(5-methyl-3-phenyl-4-isoxazolyl)benzenesulfonamide (valdecoxib), and its analogues. Thus, the coupling reaction between (3-aryl-5-methyl-4-isoxazolyl)boronic acids, prepared in situ from the corresponding bromides using triisopropyl borate, and aryl bromides containing a 4-sulfonamide or 4-methylsulfonyl group under the standard conditions [Pd(PPh3)4, Na2CO3, EtOH-H2O, reflux] yielded the target 3,4-diarylisoxazoles in good yields.
