145385-93-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145385-93-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,3,8 and 5 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 145385-93:
(8*1)+(7*4)+(6*5)+(5*3)+(4*8)+(3*5)+(2*9)+(1*3)=149
149 % 10 = 9
So 145385-93-9 is a valid CAS Registry Number.

Dienolate 11, which was produced from 3-methyl-2-phenylthio-2-butanoic acid (1), and two equivalents of LDA, reacted with aldehydes or ketones to give 5-alkyl-3-methyl-2-phenylthio-2-penten-5-olides (12) in good yields.
