Check Digit Verification of cas no

The CAS Registry Mumber 106418-48-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,4,1 and 8 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 106418-48:
(8*1)+(7*0)+(6*6)+(5*4)+(4*1)+(3*8)+(2*4)+(1*8)=108
108 % 10 = 8
So 106418-48-8 is a valid CAS Registry Number.

Synthesis and Alkali-Metal Complexing Abilities of Crown Ether Tertiary Alcohols

Pugia, Michael,Knudsen, Brian E.,Cason, C. Victor,Bartsch, Richard A.

, p. 541 - 547 (2007/10/02)

Twenty-three crown ethers with a hydroxyl and an alkyl or aryl group linked directly to the central carbon of a three-carbon bridge were synthesized in one-step reactions of glycol and bisphenol dianions with substituted 2-(chloromethyl)oxiranes.Crown ether tertiary alcohols with methyl, n-decyl, n-tetradecyl, phenyl, and p-(n-decyl)phenyl substituents and four ring sizes are prepared.The effect of substituent on Na+ and K+ complexation is assessed by the picrate extraction method for closely related tertiary crown ether alcohols with 16-crown-5 and 15-crown-5-rings.
