Check Digit Verification of cas no
The CAS Registry Mumber 77887-91-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,8,8 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 77887-91:
(7*7)+(6*7)+(5*8)+(4*8)+(3*7)+(2*9)+(1*1)=203
203 % 10 = 3
So 77887-91-3 is a valid CAS Registry Number.

FACILE ONE-POT SYNTHESIS OF HYDROXY-SUBSTITUTED CROWN ETHERS.
Ikeda,Katayama,Tsuchiya,Okahara
, p. 2473 - 2475 (1983)
Hydroxy-substituted crown ethers were prepared in one-pot synthesis by treatment of oligoethylene glycols with epichlorohydrin in the presence of alkali metals, alkali metal hydride or alkali metal hydroxides. The stability constants of complexes with sodium and potassium cations in methanol were determined.
