Check Digit Verification of cas no
The CAS Registry Mumber 295-40-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,9 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 295-40:
(5*2)+(4*9)+(3*5)+(2*4)+(1*0)=69
69 % 10 = 9
So 295-40-9 is a valid CAS Registry Number.

Solvent extraction of aqueous alkali and some heavy metal picrates with the title compounds showed that, with most cations except for Li+, Na+, and Ag+, the extractability decreases monotonically as the ring size increases from 12 to 16. However, 14-crown-4 showed the highest extractability and selectivity for Li+ over the larger alkali metals, while 15-crown-4 exhibited the highest Ag+/Tl+ selectivity.
