66514-24-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66514-24-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,5,1 and 4 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 66514-24:
(7*6)+(6*6)+(5*5)+(4*1)+(3*4)+(2*2)+(1*4)=127
127 % 10 = 7
So 66514-24-7 is a valid CAS Registry Number.

A Total Synthesis of Estradiol and its 6,6-Dimethyl Analogue
Collins, Mark A.,Jones, D. Neville
, p. 4467 - 4470 (2007/10/02)
A short, stereoselective synthesis of estradiol, and its 6,6-dimethyl analogue, was accomplished from non-steroidal starting materials.A key feature was the use of a benzothiophene unit to effect (i) the stereoselective formation of the required 8β-H c
