Check Digit Verification of cas no
The CAS Registry Mumber 161145-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,1,4 and 5 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 161145-69:
(8*1)+(7*6)+(6*1)+(5*1)+(4*4)+(3*5)+(2*6)+(1*9)=113
113 % 10 = 3
So 161145-69-3 is a valid CAS Registry Number.

Generation, rearrangements and some synthetic uses of bishomoallyllithiums
Chen, Fangping,Mudryk, Boguslaw,Cohen, Theodore
, p. 12793 - 12810 (2007/10/02)
A general preparative method for bishomoallyllithiums consists of reductive lithiation by 4,4'-di-tert-butylbiphenylide (LDBB) of bishomoallyl phenyl sulfides, which can be prepared by (1) thioacetalization of γ, δ-unsaturated ketones followed by replacin
