Check Digit Verification of cas no

The CAS Registry Mumber 265098-27-9 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, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 265098-27:
(8*2)+(7*6)+(6*5)+(5*0)+(4*9)+(3*8)+(2*2)+(1*7)=159
159 % 10 = 9
So 265098-27-9 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 (2000)

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.
