26822-25-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 26822-25-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,8,2 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 26822-25:
(7*2)+(6*6)+(5*8)+(4*2)+(3*2)+(2*2)+(1*5)=113
113 % 10 = 3
So 26822-25-3 is a valid CAS Registry Number.

Synthesis of Di- and Tetra-thiaparacyclophanes Under Phase Transfer Conditions
Singh, Paramjit,Jain, Anupa
, p. 707 - 708 (2007/10/02)
Di- and tetra-thiaparacyclophanes (3) and (4) respectively, have been synthesised using p-xylene dibromide (1) and appropriate dithiol generated in situ from dithiouronium salts (2) under liquid-liquid or solid-liquid phase transfer conditions.
