Check Digit Verification of cas no

The CAS Registry Mumber 141690-79-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,6,9 and 0 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 141690-79:
(8*1)+(7*4)+(6*1)+(5*6)+(4*9)+(3*0)+(2*7)+(1*9)=131
131 % 10 = 1
So 141690-79-1 is a valid CAS Registry Number.

Solid-phase synthesis of positively charged deoxynucleic guanidine (DNG) oligonucleotide mixed sequences

Reddy, Putta Mallikarjuna,Bruice, Thomas C.

, p. 1281 - 1285 (2007/10/03)

Positively charged DNG oligonucleotide mixed sequences containing A/T bases were prepared by solid-phase synthesis. Synthesis proceeds in 3′→5′ direction and involves coupling of 3′-Fmoc protected thiourea in the presence of HgCl2/TEA with the corresponding 5′-amine of the growing oligo chain. DNG binding characteristics with complementary DNA and with itself have been evaluated.
