86657-96-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 86657-96-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,6,5 and 7 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 86657-96:
(7*8)+(6*6)+(5*6)+(4*5)+(3*7)+(2*9)+(1*6)=187
187 % 10 = 7
So 86657-96-7 is a valid CAS Registry Number.

, p. 544 - 552 (2007/10/02)
Pummerer's ketone (1) and its 1,2-dihydro derivative 2 react with dimethylformamide dimethylacetal to yield the enaminones 5a and 6a.Amine exchange reactions lead to the compounds 5b-n (6b-n) and 7a-l (8a-l), which show interesting reactivities and stereo
