143445-91-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143445-91-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,4,4 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 143445-91:
(8*1)+(7*4)+(6*3)+(5*4)+(4*4)+(3*5)+(2*9)+(1*1)=124
124 % 10 = 4
So 143445-91-4 is a valid CAS Registry Number.

Dimesitylneopentylgermene, a new stable germene
Couret,Escudié,Delpon-Lacaze,Satgé
, p. 3176 - 3177 (2008/10/08)
The dimesitylenopentylgermene Mes2Ge= CHCH2-t-Bu (3) was synthesized in high yield by an addition-elimination reaction between dimesitylvinylfluorogermane and tert-butyllithium. It is stable at room temperature and is highly reactive toward etectrophilic and nucleophilic reagents.
