127532-91-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127532-91-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,5,3 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 127532-91:
(8*1)+(7*2)+(6*7)+(5*5)+(4*3)+(3*2)+(2*9)+(1*1)=126
126 % 10 = 6
So 127532-91-6 is a valid CAS Registry Number.

Synthesis of 10-Aryl-3a,9-dihydro-1H,3H-furobenzothiazepin-1-ones
Matsuo, Keizo,Hasuike, Yoko
, p. 2803 - 2806 (2007/10/02)
A practical synthetic route for 2-aroyl-4,4-dimehyl-2-buten-4-olides was developed. 10-Aryl-3a,9-dihydro-1H,3H-furolbenzothiazepin-1-ones were synthesized from 2-aroyl-4,4-dimethyl-2-buten-4-olides and 2-aminothiophenol in good yields.
