71305-94-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71305-94-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,3,0 and 5 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 71305-94:
(7*7)+(6*1)+(5*3)+(4*0)+(3*5)+(2*9)+(1*4)=107
107 % 10 = 7
So 71305-94-7 is a valid CAS Registry Number.

, p. 791 - 800 (2007/10/02)
The 5-hydroxy-lactar-6-en-13-oic-acid-γ-lactones (3, 11, 11a, 22a) were obtained by oxidation of their, naturally occurring, lactaro-furan derivatives (4, 13) using MCPBA or NBS.Reaction conditions, isolation of pure products and their characterization by spectral analyses are presented.
