Check Digit Verification of cas no

The CAS Registry Mumber 128405-15-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,4,0 and 5 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 128405-15:
(8*1)+(7*2)+(6*8)+(5*4)+(4*0)+(3*5)+(2*1)+(1*5)=112
112 % 10 = 2
So 128405-15-2 is a valid CAS Registry Number.

Synthesis of 2-Aminochromene Derivatives Catalyzed by KF/Al 203

Wang, Xiang-Shan,Shi, Da-Qing,Yu, Hui-Zhen,Wang, Gao-Feng,Tu, Shu-Jiang

, p. 509 - 514 (2007/10/03)

A series of 2-aminochromene derivatives include 2-aminobenzo-[h]chromene, and naphtha[1,2-b;6,5-b′]dipyrans derivatives were synthesized from arylaldehyde, malononitrile or ethyl cyanoacetate with 1-naphthol or 1,5-naphthalenediol in refluxing ethyl alcohol catalyzed by KF-A1 203. The structure of the products was confirmed by X-ray analysis.
