Check Digit Verification of cas no

The CAS Registry Mumber 171002-75-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,0,0 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 171002-75:
(8*1)+(7*7)+(6*1)+(5*0)+(4*0)+(3*2)+(2*7)+(1*5)=88
88 % 10 = 8
So 171002-75-8 is a valid CAS Registry Number.

Synthesis of 4-Arylpyridines and Substituted β-Carbolines via 1,4-Grignard-Addition to Pyridinecarboxamides.

Schlecker, Wolfgang,Huth, Andreas,Ottow, Eckhard,Mulzer, Johann

, p. 9531 - 9542 (1995)

2,5-Pyridinedicarboxamides 1 and 2, 5-bromo-3-pyridinecarboxamide 7 and 3-hydroxy-2,5-pyridinedicarboxamide 9 undergo 1,4-addition with Grignard reagents to give the 2,4,5- or 3,4,5- and 2,3,4,5-substituted pyridines 3-6, 8 and 10 after oxidation with NCS or oxygen.After selective transformation of amides 5 and 8 to carbamates 17 and 19, a modified intramolecular Golberg amide arylation furnishes the β-carbolines 22 and 24 in good yields.
