699010-88-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 699010-88-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,9,0,1 and 0 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 699010-88:
(8*6)+(7*9)+(6*9)+(5*0)+(4*1)+(3*0)+(2*8)+(1*8)=193
193 % 10 = 3
So 699010-88-3 is a valid CAS Registry Number.

Tetrasubstituted allene ethers; synthesis and use in Nazarov reactions
Tokeshi, Bradley K.,Tius, Marcus A.
, p. 786 - 790 (2007/10/03)
A method for the synthesis of tetrasubstituted allene ethers is described, making use of a reverse Brook rearrangement in the key step. The allene products have been used in the Nazarov cyclization reaction.
