Check Digit Verification of cas no
The CAS Registry Mumber 38731-83-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,7,3 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 38731-83:
(7*3)+(6*8)+(5*7)+(4*3)+(3*1)+(2*8)+(1*3)=138
138 % 10 = 8
So 38731-83-8 is a valid CAS Registry Number.

Lewis acid-catalysed one pot synthesis of substituted xanthenes
Boe, Esther,Hillringhaus, Tim,Nitsch, Jacqueline,Klussmann, Martin
, p. 1744 - 1748 (2011)
A direct synthesis of substituted xanthenes from salicylaldehydes and cyclohexenones or tetralones has been developed. The reaction is catalysed by Lewis acids like scandium triflate and furnishes substituted xanthenes in good to excellent yields using either microwave or thermal heating. Microwave heating results in significantly shortened reaction times of 30 min and generally higher yields.
