622829-38-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 622829-38-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,2,8,2 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 622829-38:
(8*6)+(7*2)+(6*2)+(5*8)+(4*2)+(3*9)+(2*3)+(1*8)=163
163 % 10 = 3
So 622829-38-3 is a valid CAS Registry Number.

Approach to the synthesis of (+)-ifforestine. Model studies directed at the tetracyclic framework
Roos, Gregory H. P.,Dastlik, Kim A.
, p. 2023 - 2044 (2007/10/03)
In order to design an effective asymmetric synthesis of (+)-ifforestine, model approaches to the construction of the tetracyclic ring system have been investigated. These studies have identified two key synthons, a functionalized isatoic anhydride and a p
