95306-18-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 95306-18-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,3,0 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 95306-18:
(7*9)+(6*5)+(5*3)+(4*0)+(3*6)+(2*1)+(1*8)=136
136 % 10 = 6
So 95306-18-6 is a valid CAS Registry Number.

A FAVORSKI REACTION USING IODOSOBENZENE
Daum, Sol J.
, p. 4725 - 4728 (2007/10/02)
Iodosobenzene or iodobenzene diacetate and excess base when reacted with 17β-hydroxy-5α-androstane-3-one (1a) unexpectedly gave a good yield of Favorski acid (3a) and some (3b). 17β-hydroxy-5α-19-norandrostan-3-one (1b) gave mainly the expected dimethylketal of the 2α-hydroxy-3-ketosteroid (5).
