1173191-30-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1173191-30-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,3,1,9 and 1 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1173191-30:
(9*1)+(8*1)+(7*7)+(6*3)+(5*1)+(4*9)+(3*1)+(2*3)+(1*0)=134
134 % 10 = 4
So 1173191-30-4 is a valid CAS Registry Number.

InBr3-catalyzed annulations of cyclic 1,3-diketones with aryl propargyl alcohols: a novel synthesis of 2,4-diaryldihydropyrans

Yadav,Subba Reddy,Raghavendra Rao,Narender

experimental part, p. 3963 - 3965 (2009/10/04)

The cyclic 1,3-dicarbonyl compounds undergo smooth cyclization with aryl propargyl alcohols in the presence of 10 mol % indium tribromide in refluxing dichloroethane to produce 2,4-diarylpyran derivatives in good yields with high selectivity.
