Check Digit Verification of cas no

The CAS Registry Mumber 39504-39-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,5,0 and 4 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 39504-39:
(7*3)+(6*9)+(5*5)+(4*0)+(3*4)+(2*3)+(1*9)=127
127 % 10 = 7
So 39504-39-7 is a valid CAS Registry Number.

Biodegradable choline hydroxide promoted environmentally benign thiolysis of epoxides

Azizi, Najmedin,Edrisi, Mahtab

supporting information, p. 525 - 528 (2016/01/20)

An environmentally benign and rapid thiolysis of epoxides using a biodegradable, choline-based task-specific ionic liquid has been developed. The ring opening reaction of aryl and alkyl epoxides proceeded rapidly and afforded the corresponding β-hydroxysulfides in high yields with excellent regioselectivity. The protocol has the advantages of easy work-up, short reaction times, high yields, and a biodegradable catalyst.

Recyclable superparamagnetic Fe3O4 nanoparticles for efficient catalysis of thiolysis of epoxides

Mojtahedi, Mohammad M.,Abaee, M. Saeed,Rajabi, Azam,Mahmoodi, Peyman,Bagherpoor, Saeed

experimental part, p. 68 - 71 (2012/08/07)

An efficient and rapid procedure is developed for room-temperature ring opening of various epoxides with thiols under solvent-free conditions in the presence of catalytic amount of superparamagnetic Fe3O4 nanoparticles. As a result,

Additive-free thiolysis of epoxides in water: A green and efficient regioselective pathway to β-hydroxy sulfides

Abaee, Saeed M.,Mojtahedi, Mohammad M.,Abbasi, Hassan,Fatemi, Ensieh R.

, p. 282 - 289 (2008/03/17)

Room-temperature ring opening of various epoxides with aromatic thiols was carried out in water in the absence of any Lewis acid or additive. High yields of β-hydroxy sulfides with excellent regioselectivity were obtained under very environmentally friend
