112621-64-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 112621-64-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,6,2 and 1 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 112621-64:
(8*1)+(7*1)+(6*2)+(5*6)+(4*2)+(3*1)+(2*6)+(1*4)=84
84 % 10 = 4
So 112621-64-4 is a valid CAS Registry Number.

, p. 358 - 360 (2007/10/02)
4-Methyl-2,6-heptanedione 1 was cyclized to enone (-)-4 via a (S)-proline-catalyzed intramolecular aldol reaction followed by dehydration.Replacement of the 4-methyl group by either an iso-propyl or a tert-butyl subtituent leads to a dramatic lowering of
