34670-08-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 34670-08-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,6,7 and 0 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 34670-08:
(7*3)+(6*4)+(5*6)+(4*7)+(3*0)+(2*0)+(1*8)=111
111 % 10 = 1
So 34670-08-1 is a valid CAS Registry Number.

Hou, Rei-Sheu,Wang, Huey-Min,Lin, Yu-Chien,Chen, Ling-Chieg
, p. 649 - 656 (2007/10/03)
The room temperature ionic liquid, n-butylpyridinium tetrafluoroborate(BPyBF4) is used as a "green" recyclable solvent for the reaction of 4-benzoylbutyric acid with [hydroxy-(2,4-dinitrobenzenesulfonyloxy)iodo]-benzene (HDNIB) to prepare 5-benzoyldihydro-2(3H)-furanone.
