5120-50-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5120-50-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,2 and 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5120-50:
(6*5)+(5*1)+(4*2)+(3*0)+(2*5)+(1*0)=53
53 % 10 = 3
So 5120-50-3 is a valid CAS Registry Number.

Nucleophilic substitution in benzylic phosphonothioic dichlorides formation of a diamide without intervention of the amidic chloride
Harger, Martin J.P.
, p. 8247 - 8248 (2007/10/03)
The diamide RP(S)(NEt2)2 (R = PhCH2 or Ph2CH) is formed directly from the dichloride RP(S)Cl2 more quickly than it is from the amidic chloride RP(S)(NEt2)Cl.
