183674-60-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 183674-60-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,6,7 and 4 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 183674-60:
(8*1)+(7*8)+(6*3)+(5*6)+(4*7)+(3*4)+(2*6)+(1*0)=164
164 % 10 = 4
So 183674-60-4 is a valid CAS Registry Number.

Synthesis of enantiopure estrone via a double heck reaction
Tietze, Lutz F.,N?bel, Thomas,Spescha, Maurus
, p. 8971 - 8977 (2007/10/03)
A novel efficient catalytic approach to steroids by a double Heck reaction of the vinyl bromides 2 and the CD-building block 3 is presented. The new estrogen analogues 1a and 1b are formed via 23a and 23b in a highly regio- and stereoselective manner in g
