Check Digit Verification of cas no

The CAS Registry Mumber 104889-75-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,8,8 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 104889-75:
(8*1)+(7*0)+(6*4)+(5*8)+(4*8)+(3*9)+(2*7)+(1*5)=150
150 % 10 = 0
So 104889-75-0 is a valid CAS Registry Number.

ISOXAZOL-ROUTE ZU CYANO-SEMIBULLVALENEN

Askani, R.,Littmann, M.

, p. 5519 - 5520 (2007/10/02)

Based on the decarboxylative ring opening of 3-carboxyisoxazoles a new reaction sequence for the introduction of cyano groups on ketone 1 a is described.The isoxazoles 4 and 5 have been obtained by the cycloaddition of carboethoxyformonitrile oxide with enamines 2 a /3 a and removal of the morpholine ring by Cope elimination.The semibullvalenes 7 and 8 were prepared.
