Check Digit Verification of cas no

The CAS Registry Mumber 132149-66-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,1,4 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 132149-66:
(8*1)+(7*3)+(6*2)+(5*1)+(4*4)+(3*9)+(2*6)+(1*6)=107
107 % 10 = 7
So 132149-66-7 is a valid CAS Registry Number.

PROCESS FOR MAKING BIARYL-BRIDGED CYCLIC PEPTIDES

-

Page/Page column 80; 81; 82, (2021/06/04)

The invention provides a method of preparing a biaryl-bridged cyclic peptide compound of Formula (I), where R1, R2, R3, R4, R5, R8, R7, R8, R9, R10, R11, R12, n and m are as defined in the specification. The biaryl-bridged cyclic peptides of Formula (I) are used in the preparation of pharmaceutically active substances, such as, for example, arylomycin and arylomycin analogues.

First total synthesis of dioxepine bastadin 3

Perez-Rodriguez, Santiago,Pereira-Cameselle, Raquel,De Lera, Angel R.

, p. 6945 - 6950,6 (2012/12/11)

The synthesis of dioxepine bastadin 3, a tyrosine-tyramine derivative with a dibenzo-1,3-dioxepine scaffold that is rarely present among natural products, is described. The dibenzo-1,3-dioxepine ring was formed early in the sequence and the (E)-2-(hydroxy

SYNTHESIS OF ANALOGUES OF THE BIPHENOMYCIN ANTIBIOTICS

Brown, Allan G.,Edwards, Peter D.

, p. 6581 - 6584 (2007/10/02)

The oxidative coupling of L-tyrosine derivatives with vanadium oxyhalides has given dityrosine intermediates which were cyclized to give analogues of the biphenomycin antibiotics.
