89615-27-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89615-27-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,6,1 and 5 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 89615-27:
(7*8)+(6*9)+(5*6)+(4*1)+(3*5)+(2*2)+(1*7)=170
170 % 10 = 0
So 89615-27-0 is a valid CAS Registry Number.

Optical resolution of anti head-to-head coumarin dimer and determination of its absolute configuration based on CD spectral data
Saigo,Sekimoto,Yonezawa,Hasegawa
, p. 5381 - 5384 (1983)
(±)-anti Head-to-head coumarin dimer was successfully resolved into a pair of optically active forms in high yields, of which the absolute configuration was determined on the basis of CD and 1H-NMR spectral data.
