118217-54-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118217-54-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,2,1 and 7 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 118217-54:
(8*1)+(7*1)+(6*8)+(5*2)+(4*1)+(3*7)+(2*5)+(1*4)=112
112 % 10 = 2
So 118217-54-2 is a valid CAS Registry Number.

ASSYMMETRIC INDUCTION IN MIXED PHOTOADDITIONS EMPLOYING α,β-UNSATURATED HOMOCHIRAL KETALS
Lange, Gordon I.,Decicco, Carl P.
, p. 2613 - 2614 (2007/10/02)
Diastereomeric excess as high as 84percent were achieved in photoadditions of methyl 3-oxo-1-cyclohexene-1-carboxylate with α,β-unsaturated homochiral ketals prepared from 2-cyclopentanone and 2R,3R-tartarate esters.
