Check Digit Verification of cas no

The CAS Registry Mumber 113975-30-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,9,7 and 5 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 113975-30:
(8*1)+(7*1)+(6*3)+(5*9)+(4*7)+(3*5)+(2*3)+(1*0)=127
127 % 10 = 7
So 113975-30-7 is a valid CAS Registry Number.

Metalation/SRN1 Coupling in Heterocyclic Synthesis. A Convenient Methodology for Ring Functionalization

Estel, L.,Marsais, F.,Queguiner, G.

, p. 2740 - 2744 (2007/10/02)

Lithiation, iodination, and fluorine substitution on 2-fluoropyridine gave 2-substituted 3-iodopyridines, which were further subjected to iodine SRN1 substitution by carbon, sulfur, and phosphorus nucleophiles.Iodine substitution by enolates on 2-amino-3-iodopyridines afforded ketones, which were further cyclized to various 1,2-disubstituted pyrrolopyridines. 2-Amino-3-iodo-, 3-amino-4-iodo, and 4-amino-3-iodopyridines were prepared by directed metalation of 2-, 3-, and 4-(pivaloylamino)pyridines.Substitution of iodine by enolates under SRN1 conditions and acidic cyclization led to various 2-substituted pyrrolo, --, and -pyridines in high yields.
