1005149-81-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1005149-81-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,5,1,4 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1005149-81:
(9*1)+(8*0)+(7*0)+(6*5)+(5*1)+(4*4)+(3*9)+(2*8)+(1*1)=104
104 % 10 = 4
So 1005149-81-4 is a valid CAS Registry Number.

Synthesis of possible o-thioquinone methide precursors
Kolmakov, Kirill A.,Kresge, A. Jerry
, p. 119 - 123 (2008/09/18)
Investigating the synthetic accessibility of o-thioquinone methide precursors containing electron donating groups, we prepared four methyl- and methoxy-substituted 2H-benzo[b]thiete derivatives by means of flash vacuum pyrolysis of the corresponding benzo
