Check Digit Verification of cas no

The CAS Registry Mumber 1370017-49-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,0,0,1 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1370017-49:
(9*1)+(8*3)+(7*7)+(6*0)+(5*0)+(4*1)+(3*7)+(2*4)+(1*9)=124
124 % 10 = 4
So 1370017-49-4 is a valid CAS Registry Number.

A facile synthetic route to new fluorinated building-blocks of 1-fluoroalkynes and 1-fluorodiynes

Liu, Cuibo,Ma, Hai,Nie, Jing,Ma, Junan

experimental part, p. 47 - 52 (2012/03/08)

A facile and direct fluorination process of alkynes and diynes was developed. In the presence of n-butyllithium, the reaction of a series of terminal alkynes and diynes with the electrophilic fluorinating reagent (NFSI) proceeded to afford various 1-fluoroalkynes and 1-fluoro-1,3-diynes in moderate to high yields.
