1215184-66-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1215184-66-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,5,1,8 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1215184-66:
(9*1)+(8*2)+(7*1)+(6*5)+(5*1)+(4*8)+(3*4)+(2*6)+(1*6)=129
129 % 10 = 9
So 1215184-66-9 is a valid CAS Registry Number.

DETERMINATION OF ENANTIOMERIC PURITY OF GLYCOLS RCHOHCH2OH
Eliel, Ernest L,Ko, Kwang-Youn
, p. 3547 - 3550 (1983)
The enantiomeric purity of primary-secondary glycols, RCHOHCH2OH, is conveniently determined by conversion to a pair of epimeric 1,3-dioxolanes through condensation with benzaldehyde, followed by nmr spectroscopy in presence of a chiral shift reagent with observation of the benzylic protons.
