185223-88-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 185223-88-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,2,2 and 3 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 185223-88:
(8*1)+(7*8)+(6*5)+(5*2)+(4*2)+(3*3)+(2*8)+(1*8)=145
145 % 10 = 5
So 185223-88-5 is a valid CAS Registry Number.

Design and synthesis of norendoxifen analogues with dual aromatase inhibitory and estrogen receptor modulatory activities

Lv, Wei,Liu, Jinzhong,Skaar, Todd C.,Flockhart, David A.,Cushman, Mark

, p. 2623 - 2648 (2015)

Both selective estrogen receptor modulators and aromatase inhibitors are widely used for the treatment of breast cancer. Compounds with both aromatase inhibitory and estrogen receptor modulatory activities could have special advantages for treatment of br

Short-step synthesis of tamoxifen and its derivatives via the three-component coupling reaction and migration of the double bond

Shiina, Isamu,Suzuki, Masahiko,Yokoyama, Kazutoshi

, p. 965 - 967 (2007/10/03)

The anti-tumor agent, tamoxifen, is easily synthesized by the successive allylation of benzaldehyde and the Friedel-Crafts alkylation reaction of anisole with the intermediary homoallyl silyl ethers, followed by the migration of the double bond to form the desired tetra-substituted ethylenes. Several derivatives of tamoxifen are also produced according to a similar synthetic strategy.
