861942-49-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 861942-49-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,1,9,4 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 861942-49:
(8*8)+(7*6)+(6*1)+(5*9)+(4*4)+(3*2)+(2*4)+(1*9)=196
196 % 10 = 6
So 861942-49-6 is a valid CAS Registry Number.

A bicyclo[3.1.1]heptano[4,3-c]pyrazole derived chiral auxiliary for dipolar cycloadditions
Molteni, Giorgio,Del Buttero, Paola
, p. 1983 - 1987 (2005)
Starting form naturally occurring (S)-cis-verbenol 1 and (1R)-(-)-myrtenol 2, we synthesised enantiopure bicyclo[3.1.1]heptano[4,3-c]pyrazole derivatives 7 and 8 via a stereoselective nitrilimine cycloaddition as the key step. The effectiveness of the abo
