Check Digit Verification of cas no
The CAS Registry Mumber 691362-81-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,1,3,6 and 2 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 691362-81:
(8*6)+(7*9)+(6*1)+(5*3)+(4*6)+(3*2)+(2*8)+(1*1)=179
179 % 10 = 9
So 691362-81-9 is a valid CAS Registry Number.

Synthesis of the 2,3,4-trisubstituted indole fragments of nosiheptide and glycothiohexide.

, p. 701 - 708 (2004)
Two routes to the protected 4-hydroxymethyl-3-methylindole-2-carboxylate fragment 17 of the thiopeptide antibiotic nosiheptide are described starting from methyl 4-methylindole-2-carboxylate 11, itself prepared in two steps, or from 3-amino-4-chlorobenzoic acid 26. The first route can be adapted to the synthesis of a fragment of the related antibiotic glycothiohexide-alpha, the 3,4-bis(hydroxymethyl)indole-2-carboxylate in which the two hydroxymethyl groups are differentiated as in indole 19 or the lactone 20.
