Check Digit Verification of cas no

The CAS Registry Mumber 79664-26-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,6,6 and 4 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 79664-26:
(7*7)+(6*9)+(5*6)+(4*6)+(3*4)+(2*2)+(1*6)=179
179 % 10 = 9
So 79664-26-9 is a valid CAS Registry Number.

Synthesis of novel deuterium labelled derivatives of N-alkylated polyamines

H?kkinen, Merja R.,Kein?nen, Tuomo A.,Khomutov, Alex R.,Auriola, Seppo,Weisell, Janne,Alhonen, Leena,J?nne, Juhani,Veps?l?inen, Jouko

experimental part, p. 547 - 562 (2009/04/07)

Novel di-, tetra- and octadeuterated derivatives of mono-N-alkylated diaminopropanes, spermidines, spermines, symmetrically bis-N-alkylated spermines and unsymmetrically bis-N-alkylated spermines were synthesized. Deuterium labels were introduced into the RHNCH2CH2CN intermediate either by exchanging the protons next to the nitrile group under basic conditions with D2O-EtOD mixture or/and by reducing the nitrile group to a CD2-NH2 fragment with LiAlD4.
