727-66-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 727-66-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,2 and 7 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 727-66:
(5*7)+(4*2)+(3*7)+(2*6)+(1*6)=82
82 % 10 = 2
So 727-66-2 is a valid CAS Registry Number.

Melamine trisulfonic acid: A new efficient catalyst for the synthesis of aryldithienylmethanes
Wu, Liqiang,Yan, Yunhui,Yan, Fulin
experimental part, p. 149 - 154 (2012/02/16)
An efficient method has been developed for the synthesis of dithienylmethanes via bisarylation of aldehydes with thiophene in the presence of melamine trisulfonic acid as a catalyst under solvent-free conditions.
