1018740-96-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1018740-96-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,8,7,4 and 0 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1018740-96:
(9*1)+(8*0)+(7*1)+(6*8)+(5*7)+(4*4)+(3*0)+(2*9)+(1*6)=139
139 % 10 = 9
So 1018740-96-9 is a valid CAS Registry Number.

Novel 1,3-dipolar cycloaddition reactions of calix[4]bis(spirodienones): synthesis of isoxazolidine derived macrocycles
Ganga,Suresh,Luxmi Varma
, p. 1750 - 1752 (2008)
Calix[4]bis(spirodienones) can perform as either 4π or 2π components in cycloaddition reactions with various carbo- and hetero-dienophiles and with 1,2-benzoquinones leading to the formation of highly functionalized macrocycles. In this Letter we report,
