Check Digit Verification of cas no
The CAS Registry Mumber 2130-76-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,3 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2130-76:
(6*2)+(5*1)+(4*3)+(3*0)+(2*7)+(1*6)=49
49 % 10 = 9
So 2130-76-9 is a valid CAS Registry Number.

Decomposition of copper-amino acid complexes by sodium sulfide
Nowshuddin, Shaik,Reddy, A. Ram
, p. 5159 - 5161 (2007/10/03)
Sodium sulfide very efficiently removes copper from protected amino acid-copper complexes. The copper in the amino acid complex was reduced to insoluble cuprous sulfide and the free amino acid was released in pure form. This method is very convenient and rapid, requiring only 5-10 min and 0.55-0.75 equiv of sodium sulfide.
