Check Digit Verification of cas no

The CAS Registry Mumber 772339-79-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,2,3,3 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 772339-79:
(8*7)+(7*7)+(6*2)+(5*3)+(4*3)+(3*9)+(2*7)+(1*9)=194
194 % 10 = 4
So 772339-79-4 is a valid CAS Registry Number.

Reaction of fluoro(phenyl)carbene with Schiff bases: Synthesis of 2-fluoro-2-phenylaziridines

Kusei,Novikov,Khlebnikov

, p. 1643 - 1647 (2007/10/03)

Fluoro(phenyl)carbene generated by reaction of α-bromo-α- fluorotoluene with potassium tert-butoxide reacts with Schiff bases to afford the corresponding 2-fluoro-2-phenylaziridines. The latter were isolated in low yields due to their instability under the carbene generation conditions. Although the reaction of α,α-dibromo-α-fluorotoluene with zinc and lead involves formation of fluoro(phenyl)carbene, this procedure is not suitable for the synthesis of 2-fluoro-2-phenylaziridines. 2005 Pleiades Publishing, Inc.
