189263-64-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 189263-64-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,2,6 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 189263-64:
(8*1)+(7*8)+(6*9)+(5*2)+(4*6)+(3*3)+(2*6)+(1*4)=177
177 % 10 = 7
So 189263-64-7 is a valid CAS Registry Number.

Construction of A and C ring intermediates for taxol by using (3+2)-cycloaddition of nitrile oxide
Takahashi, Takashi,Iwamoto, Hajime
, p. 2483 - 2486 (2007/10/03)
Syntheses of the A-ring and the chiral C-ring model of taxol by using the intramolecular nitrile oxide cycloaddition and its diastereoselectivity based on MM2 transition state model are described.
