Check Digit Verification of cas no

The CAS Registry Mumber 145657-12-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,6,5 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 145657-12:
(8*1)+(7*4)+(6*5)+(5*6)+(4*5)+(3*7)+(2*1)+(1*2)=141
141 % 10 = 1
So 145657-12-1 is a valid CAS Registry Number.

Selective Chromogenic Reagents based upon Phenolic Cryptands

Sholl, Alastair F.,Sutherland, Ian O.

, p. 1716 - 1718 (1992)

Chloroform solutions of the chromoionophore 4c, which has been synthesised by a simple procedure from diaza-15-crown-5 2a, extract lithium cations from aqueous solutions in the pH range 7-8 with very high selectivity as compared with the extraction of sodium, potassium, magnesium and calcium; the related reagent 5 shows moderate selectivity for sodium.
