Check Digit Verification of cas no

The CAS Registry Mumber 137760-78-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,7,6 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 137760-78:
(8*1)+(7*3)+(6*7)+(5*7)+(4*6)+(3*0)+(2*7)+(1*8)=152
152 % 10 = 2
So 137760-78-2 is a valid CAS Registry Number.

DIMETHYLAMINOMETHYLENE PROTECTED PURINE H-PHOSPHONATES IN THE SYNTHESIS OF BIOLOGICALLY ACTIVE RNA (24-MER)

Arnold, Lubos,Smrt, Jiri,Zajicek, Jaroslav,Ott, Guenther,Schiesswohl, Michael,Sprinzl, Mathias

, p. 1948 - 1956 (2007/10/02)

Preparation of 5'-O-(4,4'-dimethoxytrityl)-2'-O-tert-butyldimethylsilyl (tBDMSi) derivatives of N2-dimethylaminomethyleneguanosine (IIIa) and N6-dimethylaminomethyleneadenosine (IVa) and their 3'-H-phosphonates (IIIb, IVb) is described.The compounds IIIb and IVb together with corresponding derivatives of uridine (Vb) and N4-benzoylcytidine (VIb) were used as synthones in machine assisted synthesis of microhelixAla (5'-GGGGCUAUAGCUCUAGCU*CCACCA-3')((X).The compound X was aminoacylated by means of alanyl-t-RNA synthetase (E.coli).
