21186-83-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21186-83-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,8 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21186-83:
(7*2)+(6*1)+(5*1)+(4*8)+(3*6)+(2*8)+(1*3)=94
94 % 10 = 4
So 21186-83-4 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 (1980)

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
