21668-94-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21668-94-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,6,6 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 21668-94:
(7*2)+(6*1)+(5*6)+(4*6)+(3*8)+(2*9)+(1*4)=120
120 % 10 = 0
So 21668-94-0 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
