1906-01-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1906-01-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,0 and 6 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1906-01:
(6*1)+(5*9)+(4*0)+(3*6)+(2*0)+(1*1)=70
70 % 10 = 0
So 1906-01-0 is a valid CAS Registry Number.

Chlorination of 3β-hydroxyl-5-Δ steroids with anhydrous ferric chloride

Liu, Feng-Wu,Liu, Hong-Min,Zhang, Yan-Bing,Zhang, Jing-Yu,Tian, Li-Huan

, p. 825 - 830 (2007/10/03)

Treatment of 3β-hydroxyl-5-Δ steroids with anhydrous FeCl 3 in CH2Cl2 afforded reasonable yields of the corresponding alkyl chlorides with a retention of configurations. The structures of the chlorine-exchanging products were determined by NMR and HRMS spectra. The absolute configurations were confirmed by X-ray crystal analysis of 3β-chloro-androst-5-en-17-one. The generality and scope of the reaction were also investigated.
