1354545-16-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1354545-16-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,4,5,4 and 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1354545-16:
(9*1)+(8*3)+(7*5)+(6*4)+(5*5)+(4*4)+(3*5)+(2*1)+(1*6)=156
156 % 10 = 6
So 1354545-16-6 is a valid CAS Registry Number.

A novel one-pot synthesis of 3,3-diaryloxindoles
Huq,Naresh Raj
experimental part, p. 1567 - 1570 (2012/04/23)
Treatment of N-substituted isatins with various Grignard reagents gave 3,3-diaryloxindoles in good yield. The formation of 3,3-diaryloxindoles involves an unstable diol intermediate which undergoes rearrangement in the presence of an acid generated in sit
