Check Digit Verification of cas no

The CAS Registry Mumber 1241769-17-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,1,7,6 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1241769-17:
(9*1)+(8*2)+(7*4)+(6*1)+(5*7)+(4*6)+(3*9)+(2*1)+(1*7)=154
154 % 10 = 4
So 1241769-17-4 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.
