Check Digit Verification of cas no

The CAS Registry Mumber 128705-89-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,7,0 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128705-89:
(8*1)+(7*2)+(6*8)+(5*7)+(4*0)+(3*5)+(2*8)+(1*9)=145
145 % 10 = 5
So 128705-89-5 is a valid CAS Registry Number.

Intracomplex Macrocyclization: a Novel Approach to Effective Synthesis of Cryptands

Lukyanenko, Nikolay G.,Reder, Anatoly S.

, p. 1225 - 1226 (1988)

Dihydroxycryptands are formed in good yield by the reactions of N,N'-bis(oxiranylmethyl)diazacrown ethers with amines.

MACROHETEROCYCLES. 49. SIMPLE SYNTHESIS OF CRYPTANDS BASED ON INTRACOMPLEX MACROCYCLIZATION

Luk'yanenko N. G.,Reder, A. S.

, p. 1394 - 1395 (2007/10/02)

An effective method for synthesizing cryptands by reaction of bis(methylene-epoxy)diazacrown ethers with benzylamine and N,N'-dibenzylethylenediamine is reported.The good yields of cryptands are explained by formation of an intermediate in which the placement of reaction centers is favorable for intramolecular closure due to binding of the macrocycle to substrate.
