Check Digit Verification of cas no

The CAS Registry Mumber 265098-31-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,5,0,9 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 265098-31:
(8*2)+(7*6)+(6*5)+(5*0)+(4*9)+(3*8)+(2*3)+(1*1)=155
155 % 10 = 5
So 265098-31-5 is a valid CAS Registry Number.

Diastereoselective [3+2] cycloadditions of a camphor-derived chiral N- acryloylhydrazide with nitrile oxides: The preparation of optically pure δ2-isoxazolines

Yang, Kung-Shuo,Lain, Jung-Chaing,Lin, Chun-Hui,Chen, Kwunmin

, p. 1453 - 1456 (2007/10/03)

Reaction of a novel chiral N-acryloylhydrazide with various nitrile oxides proceeded smoothly to afford the cycloadduct with high diastereoselectivity (99:1). The auxiliary can be easily removed from the cycloadducts under mild conditions. (C) 2000 Elsevier Science Ltd.
