119342-90-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 119342-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,3,4 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 119342-90:
(8*1)+(7*1)+(6*9)+(5*3)+(4*4)+(3*2)+(2*9)+(1*0)=124
124 % 10 = 4
So 119342-90-4 is a valid CAS Registry Number.

Synthetic utility of HCFC-123 (2,2-dichloro-1,1,1-trifluoroethane): the reaction between HCFC-123 and aldehydes using zinc

Tamura, Masanori,Sekiya, Akira

, p. 119 - 122 (1995)

HCFC-123 (2,2-dichloro-1,1,1-trifluoroethane) reacted with zinc and aldehydes to afford predominantly either 1-substituted 2-chloro-3,3-difluoro-2-propen-1-ols or 1-substituted 2,2-dichloro-3,3,3-trifluoro-1-propanols.The reactions proceeded via 1,1-dichloro-2,2,2-trifluoroethylzinc chloride as an organozinc intermediate. - Keywords: 2,2-Dichloro-1,1,1-trifluoroethane; Reaction; Aldehydes; Zinc; 1,1-Dichloro-2,2,2-trifluoroethylzinc chloride
