49756-87-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 49756-87-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,7,5 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 49756-87:
(7*4)+(6*9)+(5*7)+(4*5)+(3*6)+(2*8)+(1*7)=178
178 % 10 = 8
So 49756-87-8 is a valid CAS Registry Number.

Clinical Analysis on Steroids. XII. Occurrence of D-Homoannulation during the Hot Acid Hydrolysis of 5β-Pregnane-3α,20α-diol Disulfate

Yoshizawa, Itsuo,Nagata, Kyoko,Oh'uchi, Ryoko,Itoh, Shinji,Kanaiwa, Yoshio,Amiya, Takashi

, p. 87 - 96 (1980)

Two D-homosteroids were isolated from the hydrolyzate of 5β-pregnane-3α,20α-diol disulfate (II) when it was refluxed in 3N hydrochloric acid.The structures of these steroids have been elucidated as 17α-methyl-D-homo-5β-androstane-3α,17aβ-diol (VI) and 17α-methyl-17aβ-chloro-D-homo-5β-androstan-3α-ol (VIII) by instrumental analyses.The former was identical with a synthetic specimen derived from 5β-pregnane-3α,20β-diol disulfate (IV) by uranediol rearrangement.The main hydrolyzates obtained were 17α-ethyl-17β-methyl-18-nor-5β-androst-13-en-3α-ol (V) and 5β-pregnane-3α-20α-diol (III).

Isolation and structural elucidation of the degradation products of pregnanediol disulfate obtained by hot acid hydrolysis (clinical analysis on steroids. XXI)
