646521-59-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 646521-59-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,6,5,2 and 1 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 646521-59:
(8*6)+(7*4)+(6*6)+(5*5)+(4*2)+(3*1)+(2*5)+(1*9)=167
167 % 10 = 7
So 646521-59-7 is a valid CAS Registry Number.

We synthesized pyrrolidino-C-nucleosides, incorporated them into oligodeoxynucleotides and investigated their pairing properties. The thermal duplex and triplex stabilities were measured. While triplex formation is destabilized in the case of pyrrolidino-
