Check Digit Verification of cas no

The CAS Registry Mumber 1258792-30-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,7,9 and 2 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1258792-30:
(9*1)+(8*2)+(7*5)+(6*8)+(5*7)+(4*9)+(3*2)+(2*3)+(1*0)=191
191 % 10 = 1
So 1258792-30-1 is a valid CAS Registry Number.

Metal-free intramolecular amination: One-pot tandem synthesis of 3-substituted 4-quinolones

Liu, Qi-Lun,Li, Qiu-Lian,Fei, Xiang-Dong,Zhu, Yong-Ming

experimental part, p. 19 - 23 (2011/04/15)

3-Substituted 4-quinolones were synthesized using a one-pot metal-free strategy in moderate to quantitative yields. Carried out in dimethylsulfoxide (DMSO) via a sequential addition of materials, the methodology is tolerant of a wide range of functional groups and applicable to library synthesis.
