Check Digit Verification of cas no
The CAS Registry Mumber 226883-66-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,6,8,8 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 226883-66:
(8*2)+(7*2)+(6*6)+(5*8)+(4*8)+(3*3)+(2*6)+(1*6)=165
165 % 10 = 5
So 226883-66-5 is a valid CAS Registry Number.

Synthesis of Substituted 1,4-Divinylbenzenes by Heck Reactions with Compressed Ethene
Detert, Heiner,Sugiono, Erli
, p. 358 - 362 (2007/10/03)
Substituted 1,4-divinylbenzenes 3a-i were synthesized by twofold Heck coupling from the corresponding 1,4-dibromo- (electron withdrawing substituents) or 1,4-diiododialkoxybenzenes 1a-i and ethene. Oligomerizations could be suppressed by increasing the pressure of ethene to 30 bar, simultaneously improving the yields of the title compounds.
