133017-23-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133017-23-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,0,1 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 133017-23:
(8*1)+(7*3)+(6*3)+(5*0)+(4*1)+(3*7)+(2*2)+(1*3)=79
79 % 10 = 9
So 133017-23-9 is a valid CAS Registry Number.

Fernandez, Franco,Garcia, Gerardo,Rodriguez, Jose E.
, p. 2837 - 2847 (2007/10/02)
A convenient synthesis of the cyclohexyl, (1R,3R,4S)-3-p-methyl and (1S-endo)-2-bornyl glyoxylates, from the respective alcohols and other very available materials, as a model applicable to that of other chiral, sensitive glyoxylates, is described.
