135998-58-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135998-58-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,9,9 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 135998-58:
(8*1)+(7*3)+(6*5)+(5*9)+(4*9)+(3*8)+(2*5)+(1*8)=182
182 % 10 = 2
So 135998-58-2 is a valid CAS Registry Number.

, p. 272 - 277 (2007/10/02)
The oximes of 3,4-diarylspiro-1'-ones through the action of hydroxylamine-sodium acetate mixture in ethanol were synthesized.By Beckmann rearrangement on these oximes we obtained the 3,4-diaryl-5-(2-cyano-benzyl)-isoxazoles.The
