The CAS Registry Mumber 1262020-28-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,0,2 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1262020-28:
(9*1)+(8*2)+(7*6)+(6*2)+(5*0)+(4*2)+(3*0)+(2*2)+(1*8)=99
99 % 10 = 9
So 1262020-28-9 is a valid CAS Registry Number.

Water-promoted, silver-phosphine complex-catalyzed stereoselective cyclization of 2-(1-Hydroxy-3-arylprop-2-ynyl)phenols leading to a highly efficient approach to aurones

Lin, Mingdeng,Yu, Min,Han, Chengyan,Li, Chao-Jun,Yao, Xiaoquan

body text, p. 3228 - 3236 (2011/09/30)

Silver-phosphine complexes can be utilized as highly efficient catalysts for the cyclization of 2-(1-hydroxy-3-arylprop-2-ynyl)phenols (1) to give product 2, key intermediates to synthesize aurones (4), with good yields and stereoselectivities in water-to
