Check Digit Verification of cas no

The CAS Registry Mumber 16835-77-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,3 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 16835-77:
(7*1)+(6*6)+(5*8)+(4*3)+(3*5)+(2*7)+(1*7)=131
131 % 10 = 1
So 16835-77-1 is a valid CAS Registry Number.

Complexation of Calcium by α-Isosaccharinic Acid under Alkaline Conditions

Vercammen, Karlien,Glaus, Martin Alfred,Van Loon, Luc Robert

, p. 241 - 246 (2007/10/03)

The complexation of Ca2+ by α-isosaccharinic acid (α-ISA) was determined by measuring the solubility of Ca(α-ISA)2 as a function of pH. In the pH range between 12 and 12.8, the observed increase of the total concentration of Ca in solution with increasing pH is explained by the complexation reaction: Ca2+ + α-ISA- ? Ca(α-ISA-H)0 + H+ with log KoCaISA0= -10.4 (s = 0.2) at I = 0. In addition to this complexation reaction, another complex is postulated: Ca2+ + α-ISA- ? Ca(α-ISA)+ with log KoCaISA+ = 1.70. A value for the solubility product of Ca(α-ISA)2 is calculated: log Kosol = -6.36 (s = 0.1) at I = 0.
