Check Digit Verification of cas no

The CAS Registry Mumber 1219744-25-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,9,7,4 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1219744-25:
(9*1)+(8*2)+(7*1)+(6*9)+(5*7)+(4*4)+(3*4)+(2*2)+(1*5)=158
158 % 10 = 8
So 1219744-25-8 is a valid CAS Registry Number.

Highly stereoselective 7-endo-trig /ring contraction cascade to construct pyrrolo[1,2- a ]quinoline derivatives

Li, Xinyu,Li, Cheng,Zhang, Wenjing,Lu, Xiang,Han, Shiqing,Hong, Ran

supporting information; experimental part, p. 1696 - 1699 (2010/09/05)

With the cooperation of Cram's phenonium ion, a novel cascade reaction was illustrated to construct pyrrolo[1,2-a]quinolines as a sole diastereoisomer in good to excellent yields. Preliminary mechanistic studies revealed that the γ-lactam ring and electron-rich arene are important driving forces for ring contraction.
