162356-20-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 162356-20-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,3,5 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 162356-20:
(8*1)+(7*6)+(6*2)+(5*3)+(4*5)+(3*6)+(2*2)+(1*0)=119
119 % 10 = 9
So 162356-20-9 is a valid CAS Registry Number.

Chiral (-)-coniceine and (S)-pyrrolam A were synthesized from dienes prepared from L-proline by ring closure metathesis.

Stereochemical consequences of the Lewis acid-promoted 3-aza-cope rearrangement of N-alkyl-N-allyl enamines

Cook, Ggregory R.,Stille, John R.

, p. 4105 - 4124 (2007/10/02)

Internal and relative asymmetric induction were examined for the electrophile promoted 3-aza-Cope rearrangement of substituted N-alkyl-N-allyl enamines. In general, internal asymmetric induction was highly variable, and was dependent both upon the nature
