186820-80-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 186820-80-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,8,2 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 186820-80:
(8*1)+(7*8)+(6*6)+(5*8)+(4*2)+(3*0)+(2*8)+(1*0)=164
164 % 10 = 4
So 186820-80-4 is a valid CAS Registry Number.

Enantioselective Synthesis of (R)-(+)-Pulvilloric Acid
Roedel, Thomas,Gerlach, Hans
, p. 213 - 216 (2007/10/03)
The fungal metabolite (R)-(+)-pulvilloric acid was synthesized for the first time.Reaction of the Grignard reagent of 5 with 2-pentyloxirane (S)-(-)-4 in the presence of 1,5-cyclooctadienecopper(I) chloride as the catalyst led to (S)-(+)-6.The ena
