1257405-97-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1257405-97-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,4,0 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1257405-97:
(9*1)+(8*2)+(7*5)+(6*7)+(5*4)+(4*0)+(3*5)+(2*9)+(1*7)=162
162 % 10 = 2
So 1257405-97-2 is a valid CAS Registry Number.

, p. 626 - 631 (2011/02/17)
New 4-(2-hydroxymethylaryl)coumarins were prepared using the Suzuki-Miyaura cross- coupling at the key step. According to X-ray diffraction data, the compounds obtained are structural analogs of the natural stilbene combretastatin A-4, which exhibits potent antitumor activity.
