249751-75-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 249751-75-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,9,7,5 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 249751-75:
(8*2)+(7*4)+(6*9)+(5*7)+(4*5)+(3*1)+(2*7)+(1*5)=175
175 % 10 = 5
So 249751-75-5 is a valid CAS Registry Number.

Synthesis of mixed chalcogenido-bridged dirhenium complexes of the type Re2(μ-ER)(μ-E′R′)(CO)8 (E, E′ = S, Se, Te; R, R′ = org. Residue)
Egold, Hans
, p. 2295 - 2305 (2008/10/08)
Hydrido sulfido bridged complexes Re2(μ-H)-(μ-SR)(CO)8 (R = Ph, naph, Cy) react with the base DBU to give the salts [DBUH][Re2(μ-SR)(CO)8]. Upon addition of electrophiles R′E′Br (E′R = SPh, SePh, TePh) to the in
