368423-72-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 368423-72-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,6,8,4,2 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 368423-72:
(8*3)+(7*6)+(6*8)+(5*4)+(4*2)+(3*3)+(2*7)+(1*2)=167
167 % 10 = 7
So 368423-72-7 is a valid CAS Registry Number.

Synthesis and absolute stereochemistry of roseophilin
Harrington,Tius
, p. 8509 - 8514 (2007/10/03)
The enantiospecific total synthesis of natural roseophilin has been completed in 7.0% overall yield over 15 steps by means of an asymmetric cyclopentannelation. This establishes the absolute configuration of the natural product as 22R,23R. Cyclopentenone
