130288-81-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 130288-81-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,2,8 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 130288-81:
(8*1)+(7*3)+(6*0)+(5*2)+(4*8)+(3*8)+(2*8)+(1*1)=112
112 % 10 = 2
So 130288-81-2 is a valid CAS Registry Number.

A Convenient Approach to the Synthesis of Deoxyribonucleoside-3'-hydrogen Phosphonates via Bis(1,1,1,3,3,3-hexafluoro-2-propyl) Phosphonate Intermediate

Takaku, Hiroshi,Yamakage, Shunitchy,Sakatsume, Osamu,Ohtsuki, Michiya

, p. 1675 - 1678 (1988)

Transesterification of a new reagent, bis(1,1,1,3,3,3-hexafluoro-2-propyl)phosphonates was found to be very effective for the preparation of deoxyribonucleoside-3'-hydrogen phosphonates.The yields of deoxyribooligonucleotides by the H-phosphonate method o

Oxidative and nonoxidative formation of internucleotide linkages

Brill,Yau,Caruthers

, p. 6621 - 6624 (2007/10/02)

Activation of nucleoside 3'-hydrogenphosphonodithioates with iodine in the presence of nucleosides and amines yields dinucleoside phosphorodithioates and nucleoside phosphorodithioamidates, respectively. Similar activation of nucleoside 3'-methylphosphono
