77273-75-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77273-75-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,7 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 77273-75:
(7*7)+(6*7)+(5*2)+(4*7)+(3*3)+(2*7)+(1*5)=157
157 % 10 = 7
So 77273-75-7 is a valid CAS Registry Number.

Scandium triflate-catalyzed one-pot domino approach towards general and efficient syntheses of unsymmetrical 9-substituted xanthene derivatives

Singh, Ritesh,Panda, Gautam

experimental part, p. 1097 - 1105 (2010/06/15)

A general and efficient one-pot cascade/tandem approach to synthesize unsymmetrical 9-aryl/heteroaryl xanthenes has been developed under extremely mild reaction conditions using 10 mol% Sc(OTf)3 as a catalyst. This strategy has been further extended to synthesize 9-(thioaryl) xanthenes through tandem carbon-sulfur (C-S) and carbon-carbon (C-C) bond formation. Novel C-C and C-S bond cleavage promoted by Sc(OTf)3 is also discussed during mechanistic investigation. The Royal Society of Chemistry.
