Check Digit Verification of cas no

The CAS Registry Mumber 33665-27-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,6,6 and 5 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 33665-27:
(7*3)+(6*3)+(5*6)+(4*6)+(3*5)+(2*2)+(1*7)=119
119 % 10 = 9
So 33665-27-9 is a valid CAS Registry Number.

Isomerization of alkynemono-ols catalyzed by palladium(0) complex and diols

Lu, Xiyan,Ji, Jianguo,Guo, Cheng,Shen, Wei

, p. 259 - 266 (2007/10/02)

Isomerization of alkynemono-ols occurred by the catalysis of Pd2(dba)3 * CHCl3 (1) + iPr3P + HOCH2CH2OH.Palladium hydride active species were supposed to be formed in situ by the oxidative addition of diols to 1 as determined bu 1H NMR spectra.
