Check Digit Verification of cas no
The CAS Registry Mumber 1461634-39-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,6,1,6,3 and 4 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1461634-39:
(9*1)+(8*4)+(7*6)+(6*1)+(5*6)+(4*3)+(3*4)+(2*3)+(1*9)=158
158 % 10 = 8
So 1461634-39-8 is a valid CAS Registry Number.

A novel reaction of gem-difluorocyclopropyl ketones with nitriles leading to 2-fluoropyrroles
Yang, Tang-Po,Lin, Jin-Hong,Chen, Qing-Yun,Xiao, Ji-Chang
supporting information, p. 9833 - 9835 (2013/10/21)
The CF3SO3H-promoted ring opening of gem-difluorocyclopropyl ketones prefers to undergo proximal bond cleavage and the subsequent cyclization with nitriles occurred smoothly to give 2-fluoropyrroles.
