Check Digit Verification of cas no

The CAS Registry Mumber 130052-47-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,0,5 and 2 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 130052-47:
(8*1)+(7*3)+(6*0)+(5*0)+(4*5)+(3*2)+(2*4)+(1*7)=70
70 % 10 = 0
So 130052-47-0 is a valid CAS Registry Number.

Regio- and stereoselective incorporation of a13C nuclide into D-ribo-phytosphingosine via SmI2-mediated C-C formation with13C-labeled isocyanide

Murakami, Masahiro,Ito, Hajime,Ito, Yoshihiko

, p. 185 - 186 (2007/10/03)

Preparation of a 13C-labeled isocyanide and its application to the total synthesis of [2-13C]D-ribo-C18-phytosphingosine are described. The synthesis of the labeled phytosphingosine is based on the use of the isocyanide as a 13CH-NH2 precursor in the SmI2-mediated three-component coupling reaction, wherein regio- and stereoselective incorporation of a 13C nuclide in the carbon skeleton is achieved.
