Check Digit Verification of cas no
The CAS Registry Mumber 805-26-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,0 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 805-26:
(5*8)+(4*0)+(3*5)+(2*2)+(1*6)=65
65 % 10 = 5
So 805-26-5 is a valid CAS Registry Number.

Palladium-Catalyzed Ortho-Arylation of Carbamate-Protected Estrogens
Bedford, Robin B.,Brenner, Peter B.,Durrant, Steven J.,Gallagher, Timothy,Méndez-Gálvez, Carolina,Montgomery, Michelle
, p. 3473 - 3478 (2016)
The palladium-catalyzed ortho-arylation of diethyl carbamate-protected estrone and estriol with aryl iodides gives the 2-arylated analogues. Subsequent removal of the carbamate directing group furnishes 2-arylated estrone, estradiol, or estriol depending on the method used.
