Check Digit Verification of cas no

The CAS Registry Mumber 1086703-22-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,8,6,7,0 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1086703-22:
(9*1)+(8*0)+(7*8)+(6*6)+(5*7)+(4*0)+(3*3)+(2*2)+(1*2)=151
151 % 10 = 1
So 1086703-22-1 is a valid CAS Registry Number.

Intramolecular suzuki-miyaura reaction for the total synthesis of signal peptidase inhibitors, arylomycins A2and B2

Dufour, Jeremy,Neuville, Luc,Zhu, Jieping

supporting information; experimental part, p. 10523 - 10534 (2010/11/04)

Development of the total syntheses of arylomycins A1 and B 2 is detailed. Key features of our approach include 1) formation of 14-membered meta, meta-cyclophane by an intramolecular Suzuki-Miyaura reaction; 2) incorporation of N-Me-4-hydroxyphenylglycine into the cyclization precursor, which avoids the late-stage low-yielding N-methylation step; 3) segment coupling of a fully elaborated peptide side chain to the macrocycle, which makes the synthesis highly convergent. Overall, arylomycin A2 was obtained in 13 steps from L-Tyr for the longest linear sequence, in 13% overall yield. Arylomycin B2 was synthesized in 10 steps from L-3-nitro-Tyr, in 10% overall yield.
