Check Digit Verification of cas no

The CAS Registry Mumber 627535-87-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,7,5,3 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 627535-87:
(8*6)+(7*2)+(6*7)+(5*5)+(4*3)+(3*5)+(2*8)+(1*7)=179
179 % 10 = 9
So 627535-87-9 is a valid CAS Registry Number.

Rapid and diverse route to natural product-like biaryl ether containing macrocycles

Cristau, Pierre,Vors, Jean-Pierre,Zhu, Jieping

, p. 7859 - 7870 (2007/10/03)

A two-step sequence involving an Ugi four-component reaction and an intramolecular nucleophilic aromatic substitution (SNAr) has been developed for the rapid access to biaryl-ether containing macrocycles. In the course of this study, we documented that ammonium chloride can promote the Ugi-4CR in non-polar aprotic solvent (toluene) without the interference of an alternative Passerini reaction. Solid phase synthesis of macrocycles by this two-step sequence was also developed using polymer (Wang resin) supported α-(4′-fluoro-3′-nitro)phenethyl isocyanoacetate as one of the inputs.
