64650-34-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 64650-34-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,6,5 and 0 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 64650-34:
(7*6)+(6*4)+(5*6)+(4*5)+(3*0)+(2*3)+(1*4)=126
126 % 10 = 6
So 64650-34-6 is a valid CAS Registry Number.

Copper mediated formation of carbon-heteroatom bonds using organoboron reagents and ultrasound

Musolino, Bryan J.,Kabalka, George W.

, p. 271 - 297 (2015/03/04)

This report summarizes research efforts focused on copper acetate mediated reactions to form new carbon-heteroatom bonds using organoboron reagents under ultrasound irradiation. The method involves the application of ultrasound irradiation to the Chan-Evans-Lam reaction to achieve O-arylation of phenols, N-arylation of anilines and indoles, and S-arylation of thiols. Ultrasound irradiation was found to decrease reaction times from 72 hours to 4 hours while improving the product yields an average of 20%.1 Representative C-O, C-N, and C-S coupling reactions were successfully scaled-up from the milligram to gram levels while maintaining good product yields offering potential applications in industrial processes.
