240122-41-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 240122-41-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,0,1,2 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 240122-41:
(8*2)+(7*4)+(6*0)+(5*1)+(4*2)+(3*2)+(2*4)+(1*1)=72
72 % 10 = 2
So 240122-41-2 is a valid CAS Registry Number.

, p. 4701 - 4702 (1999)
The first asymmetric total synthesis of (-)-virgatusin, a new furanolignan, isolated from phyllanthus virgatus, was accomplished in a stereoselective manner by nucleophilic addition of organolithium reagent to the functionalized lactone elaborated from di
