150291-98-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 150291-98-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,0,2,9 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 150291-98:
(8*1)+(7*5)+(6*0)+(5*2)+(4*9)+(3*1)+(2*9)+(1*8)=118
118 % 10 = 8
So 150291-98-8 is a valid CAS Registry Number.

Thermal Conversion of Phorone into Isophorone via (Trimethylsilyl)oxyhexatriene (SOH) Cyclization
Torok, Daniel S.,Scott, William J.
, p. 3067 - 3070 (2007/10/02)
Heating of 3-Z-4-(trimethylsilyl)oxy-2,6-dimethylhepta-1,3,5-triene, readily available from phorone (LDA; TMSCl), at 220 deg C caused isomerization and cyclization to afford isophorone after deprotection.
