Check Digit Verification of cas no

The CAS Registry Mumber 1451153-07-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,1,1,5 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1451153-07:
(9*1)+(8*4)+(7*5)+(6*1)+(5*1)+(4*5)+(3*3)+(2*0)+(1*7)=123
123 % 10 = 3
So 1451153-07-3 is a valid CAS Registry Number.

Synthesis of polyfluoroalkyl cyclobutenes from 3-aza-1,5-enynes via an aza-Claisen rearrangement/cyclization cascade

Xin, Xiaoyi,Wang, Dongping,Wu, Fan,Wang, Chunxiang,Wang, Haolong,Li, Xincheng,Wan, Boshun

, p. 4512 - 4515 (2013)

A facile synthetic route to access polyfluoroalkyl functionalized cyclobutenes bearing an exo cyclic double bond from 3-aza-1,5-enynes is reported. The reaction proceeds via a thermal aza-Claisen rearrangement to give an allene-imine intermediate; subsequent cyclization affords the cyclobutene core. The kinetics of the transformation of starting material and the intermediate was studied by 1H NMR spectroscopy, where a consecutive reaction was revealed.
