123355-83-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 123355-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,3,5 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 123355-83:
(8*1)+(7*2)+(6*3)+(5*3)+(4*5)+(3*5)+(2*8)+(1*3)=109
109 % 10 = 9
So 123355-83-9 is a valid CAS Registry Number.

Asymetric Electrophilic α-Amidoalkylation, VII: Generation, Crystal Structure, and Trapping Reactions of a Chiral 6,7-Dimethoxy-1,2,3,4-tetrahydroisoquinoline Derived N-Acyliminium Ion

Wanner, Klaus Th.,Praschak, Ilona,Nagel, Ulrich

, p. 335 - 350 (2007/10/02)

The camphanic acid amide 4 has efficiently been oxidized with triphenylcarbenium tetrafluoroborate (3) to yield the chiral N-acyliminium ion 1.Trapping reactions of 1 with the silyl nucleophiles 7a-c and 10a-f proceeded with stereoselective bond formation
