99932-25-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99932-25-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,9,3 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 99932-25:
(7*9)+(6*9)+(5*9)+(4*3)+(3*2)+(2*2)+(1*5)=189
189 % 10 = 9
So 99932-25-9 is a valid CAS Registry Number.

THE SYNTHESIS OF 2-CHLOROPHENYL DERIVATIVES OF GROUP V
Al-Jabar, N. A. A.,Massey, A. G.
, p. 145 - 148 (2007/10/02)
The thermal stability of 2-chlorophenyllithium can be markedly increased by the addition of tetramethylethylene diamine, thus allowing its use in the high yield synthesis of tris(2-chlorophenyl) derivatives of the Group V elements.
