66341-26-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66341-26-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,3,4 and 1 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 66341-26:
(7*6)+(6*6)+(5*3)+(4*4)+(3*1)+(2*2)+(1*6)=122
122 % 10 = 2
So 66341-26-2 is a valid CAS Registry Number.

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.
