Check Digit Verification of cas no

The CAS Registry Mumber 197015-32-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,0,1 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 197015-32:
(8*1)+(7*9)+(6*7)+(5*0)+(4*1)+(3*5)+(2*3)+(1*2)=140
140 % 10 = 0
So 197015-32-0 is a valid CAS Registry Number.

Construction of spirofused tricyclic frameworks by NHC-catalyzed intramolecular stetter reaction of a benzaldehyde tether with a cyclic exsnone

Hsu, Day-Shin,Cheng, Chiao-Yun

, p. 10832 - 10842 (2019/09/30)

Various benzaldehyde tethers with a cyclic enone were prepared from commercially available 2-hydroxybenzaldehydes via a three-step sequence involving triflate formation, Sonogashira cross-coupling, and regioselective hydrogenation. These substrates were t

experimental part, p. 2533 - 2536 (2011/05/15)

A new class of benzoxaborole β-lactamase inhibitors were designed and synthesized. 6-Aryloxy benzoxaborole 22 inhibited AmpC P99 and CMY-2 with K i values in the low nanomolar range. Compound 22 restored antibacterial activity of ceftazidime against Enterobacter cloacae P99 expressing AmpC, a class C β-lactamase enzyme. The SAR around the arylbenzoxaboroles, which included the influence of linker and substitutions was also established.
