93844-99-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93844-99-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,8,4 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 93844-99:
(7*9)+(6*3)+(5*8)+(4*4)+(3*4)+(2*9)+(1*9)=176
176 % 10 = 6
So 93844-99-6 is a valid CAS Registry Number.

STANNOUS (II) TRIFLATE PROMOTED REARRANGEMENT OF β-KETO SULFOXIDES. SYNTHESIS OF 1,4-DIKETONES
Shimizu, Makoto,Akiyama, Takahiko,Mukaiyama, Teruaki
, p. 1531 - 1534 (2007/10/02)
Stannous triflate promotes rearrangement of β-keto sulfoxides to generate α-thiocarbocation, which in turn react with silyl enol ethers to give 2-arylsulfenyl-1,4-diketones in good yields.
