104236-61-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 104236-61-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,2,3 and 6 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 104236-61:
(8*1)+(7*0)+(6*4)+(5*2)+(4*3)+(3*6)+(2*6)+(1*1)=85
85 % 10 = 5
So 104236-61-5 is a valid CAS Registry Number.

Dithiaphosphagermetannes-1,3,2,4 et dithiaphosphadigermolannes-1,4,5,2,3

Barrau, J.,Amine, M. El,Rima, G.,Satge, J.

, p. 615 - 620 (2007/10/02)

The synthesis of the new germylated and phosphorylated heterocycles 2-anisyl-4,4-dimethyl-2-thio-1,3,2,4-dithiaphosphagermetane, (1), and 5-anisyl-2,2,3,3-tetramethyl-5-thio-1,4,5,2,3-dithiaphosphadigermolane, (2), are described.The decomposition of 1 with formation of (Me2GeS)3 and (AnPS2)n is observed at room temperature.At 200 deg C 2 undergoes thermal fragmentation leading to (Me2GeS)3 and (AnPS)n.These results are explained by two mechanisms of decomposition involving formation of transient species and or , respectively.Exchange reactions between 2 and various metal (MIVB) chlorides are described.With Me2SiCl2 the reaction leads to silathione , probably via transient dithiaphosphasiletane.
