23092-12-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 23092-12-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,0,9 and 2 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 23092-12:
(7*2)+(6*3)+(5*0)+(4*9)+(3*2)+(2*1)+(1*2)=78
78 % 10 = 8
So 23092-12-8 is a valid CAS Registry Number.

Synthesis of Unsymmetrical Δ4,4'-Bi-4H-pyrans and -thiopyrans
Reynolds, George A.,Chen, Chin H.
, p. 2458 - 2459 (2007/10/02)
Unsymmetrical Δ4,4'-bi-4H-pyrans and -thiopyrans are prepared from the Wittig reagent which is derived from (4H-pyran-4-yl)triphenylphosphonium salts or the thio analogues by allowing the reagent to react with a pyrylium or thiopyrylium salt wi
