Check Digit Verification of cas no

The CAS Registry Mumber 82109-84-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,1,0 and 9 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 82109-84:
(7*8)+(6*2)+(5*1)+(4*0)+(3*9)+(2*8)+(1*4)=120
120 % 10 = 0
So 82109-84-0 is a valid CAS Registry Number.

Studies on Organic Fluorine Compounds. 38. Ring-Opening Reactions of gem-Difluorocyclopropyl Ketones with Nucleophiles

Kobayashi, Yoshiro,Taguchi, Takeo,Morikawa, Tsutomu,Takase, Toyohiko,Takanashi, Hiroshi

, p. 3232 - 3236 (2007/10/02)

Syntheses of gem-difluorocyclopropyl ketones (3a-d) and their reactions with nucleophiles are described.Ring-opening reaction of 3a,c,d having a hydrogen substituent at C1 adjacent to the carbonyl group with a methanolate anion gave carboxylic acid derivatives derived from C1-C2 bond scission (between the carbon atom with an acyl group and the carbon atom with fluorine substituents).On the other hand, reaction of 3a-c with a thiolate anion resulted in the C1-C3 bond cleavage (carbon-carbon bond opposite to the difluoromethylene group).

RING OPENING REACTION OF gem-DIFLUOROCYCLOPROPYL KETONES WITH NUCLEOPHILES

Kobayashi, Yoshiro,Taguchi, Takeo,Morikawa, Tsutomu,Takase, Toyohiko,Takanashi, Hiroshi

, p. 1047 - 1050 (2007/10/02)

Syntheses of gem-difluorocyclopropyl ketones (3a-d) and their reactions with nucleophiles are described.Ring opening reactions of 3a, c and d with a methanolate and a thiolate anion took entirely different courses of bond scission of the cyclopropane ring.
