128099-22-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128099-22-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,0,9 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 128099-22:
(8*1)+(7*2)+(6*8)+(5*0)+(4*9)+(3*9)+(2*2)+(1*2)=139
139 % 10 = 9
So 128099-22-9 is a valid CAS Registry Number.

The title compounds (1) undergo a -PhS shift to give an E,Z mixture of vinyl sulphides (2) with thionyl chloride but only the Z isomer if toluene-p-sulphonic acid is used.The reaction occurs only if another PhS group is present β to the hydroxyl.The
