350037-73-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 350037-73-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,0,0,3 and 7 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 350037-73:
(8*3)+(7*5)+(6*0)+(5*0)+(4*3)+(3*7)+(2*7)+(1*3)=109
109 % 10 = 9
So 350037-73-9 is a valid CAS Registry Number.

Stereoselective synthesis of novel 19-nor-steroids by a double Heck reaction
Tietze, Lutz F.,Petersen, Soenke
, p. 1619 - 1624 (2007/10/03)
The estrane 4 was synthesized by two successive Heck reactions starting from enantiopure 2 and the cyclohexenone 5, which contains a (Z)-bromovinyl group. The first intermolecular Pd-catalyzed reaction leads to 10 in a highly regio and diastereoselective
