128237-82-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128237-82-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,2,3 and 7 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 128237-82:
(8*1)+(7*2)+(6*8)+(5*2)+(4*3)+(3*7)+(2*8)+(1*2)=131
131 % 10 = 1
So 128237-82-1 is a valid CAS Registry Number.

Synthesis of 2,5-dihydro-2,5-diphenylfuran
Jack, Ibiba R.
, p. 915 - 917 (2007/10/02)
2,5-Dihydro-2,5-diphenylfuran (4) has been synthesized by the reaction of phenylmagnesium bromide with 2,5-dibromo-2,5-dihydrofuran (3).Reaction of 2,5-dihydro-2,5-dimethoxyfuran (1) with phenylmagnesium bromide and phenyllithium however leads to ring ope
