162409-89-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 162409-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,4,0 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 162409-89:
(8*1)+(7*6)+(6*2)+(5*4)+(4*0)+(3*9)+(2*8)+(1*9)=134
134 % 10 = 4
So 162409-89-4 is a valid CAS Registry Number.

Synthesis of cryptocaryalactone, a 1,3-polyol-derived unsaturated lactone
Mori,Furukawa
, p. 2161 - 2163 (2007/10/02)
Cryptocaryalactone, a 1,3-polyol-derived α,β-unsaturated δ-lactone, has been synthesized in a stereocontrolled manner via the coupling reaction of a chiral dithiane with an epoxide and anti-stereoselective 1,3-asymmetric reduction of the derived hydroxy k
