Check Digit Verification of cas no

The CAS Registry Mumber 92144-77-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,1,4 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 92144-77:
(7*9)+(6*2)+(5*1)+(4*4)+(3*4)+(2*7)+(1*7)=129
129 % 10 = 9
So 92144-77-9 is a valid CAS Registry Number.

Molecular design of crown ethers. VII.1 syntheses and cation selectivities of unsubstituted 12- To 16-crown-4

Liu, Yu,Inoue, Yoshihisa,Hakushi, Tadao

, p. 3044 - 3046 (1990)

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.
