19741-72-1 Usage
General Description
3-Methoxy-18-methylestra-2,5(10)dien-17-one 17-ethylene ketal is a synthetic chemical compound that belongs to the group of estrogen hormones. It is a derivative of estradiol with a methoxy and ethylene ketal group attached to the C17 position of the steroid nucleus. 3-Methoxy-18-methylestra-2,5(10)dien-17-one 17-ethylene ketal has potential applications in medicinal and pharmaceutical research, particularly in the development of hormone-based therapies and treatments for conditions related to hormone imbalances. Its structure and properties make it a promising candidate for further study and potential therapeutic use.
Check Digit Verification of cas no
The CAS Registry Mumber 19741-72-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,7,4 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 19741-72:
(7*1)+(6*9)+(5*7)+(4*4)+(3*1)+(2*7)+(1*2)=131
131 % 10 = 1
So 19741-72-1 is a valid CAS Registry Number.

SILICA GEL PROMOTED SELECTIVE HYDROLYSIS OF 3-METHOXY-2,5(10)-DIENE STEROIDS
Lui, Li-Gong,Zhang, Tong,Li, Zhen-Su
, p. 2999 - 3006 (2007/10/03)
Hydrolysis of 3-methoxy-2,5(10)-diene steroids (1a-c) via oxalic acid in the presence of silica gel was developed as a fast selective synthesis method toward corresponding 5(10)-en-3-ones (2a-c) in good yield (51-94percent).This also provided a new method for selective ketalisation of 17-keto over 3-keto (2c).
