104702-05-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104702-05-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,7,0 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 104702-05:
(8*1)+(7*0)+(6*4)+(5*7)+(4*0)+(3*2)+(2*0)+(1*5)=78
78 % 10 = 8
So 104702-05-8 is a valid CAS Registry Number.

Cytochalasan synthesis: Total synthesis of cytochalasin H
Thomas, Eric J.,Whitehead, John W. F.
, p. 507 - 518 (2007/10/02)
Cytochalasin H (2) has been synthesized using an intramolecular Diels-Alder reaction to form the [11]cytochalasan skeleton. This was highly stereoselective and gave adduct (49) with the correct configurations at all chiral centres. The later stages of the
