650619-69-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 650619-69-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,0,6,1 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 650619-69:
(8*6)+(7*5)+(6*0)+(5*6)+(4*1)+(3*9)+(2*6)+(1*9)=165
165 % 10 = 5
So 650619-69-5 is a valid CAS Registry Number.

, p. 51 - 54 (2007/10/03)

(Equation presented) Nucleotide building blocks with two base moieties were synthesized and incorporated into oligonucleotides. One of the two bases is involved in base pairing within the double helix, while the other base is sticking out of the minor groove. This system may be used for presenting sequence information at the outside of the helix.
