Check Digit Verification of cas no
The CAS Registry Mumber 1189378-13-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,3,7 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1189378-13:
(9*1)+(8*1)+(7*8)+(6*9)+(5*3)+(4*7)+(3*8)+(2*1)+(1*3)=199
199 % 10 = 9
So 1189378-13-9 is a valid CAS Registry Number.

Regioselective cleavage of 2-aryloxymethyloxiranes to 3-aryloxy-l- halogenopropan-2-ols
Maciejewski,Poltorak,Kaminska
experimental part, p. 595 - 604 (2009/12/26)
A series of new 2-ary loxymethy loxiranes prepared from epichlorohydrin and substituted phenols was subjected to nucleophilic opening of the oxirane ring. A comparison of regioselectivity and product yield for oxirane cleavage by means of aqueous hydrohalogenic acids or lithium tetrahalogenocuprates under anhydrous conditions was performed. The latter method provided very high regioselectivity for 3-aryloxy-l-halo-genopropan-2-ols as well as excellent yields.
