74966-52-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74966-52-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,6 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 74966-52:
(7*7)+(6*4)+(5*9)+(4*6)+(3*6)+(2*5)+(1*2)=172
172 % 10 = 2
So 74966-52-2 is a valid CAS Registry Number.

Rearrangement Chemistry of the α-Diazo Ketone Derived from 2,2,5,5-Tetramethylthiolane-3,4-dione
Bolster, J.,Kellogg, Richard M.
, p. 4804 - 4805 (1980)
The α-diazo ketone of 2,2,5,5-tetramethylthiolane-3,4-dione undergoes both thermally and photochemically induced rearrangement; the chief product, a thietanone derivative, undergoes smooth and rapid photochemically induced fragmentation.
