Check Digit Verification of cas no

The CAS Registry Mumber 71989-17-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,9,8 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 71989-17:
(7*7)+(6*1)+(5*9)+(4*8)+(3*9)+(2*1)+(1*7)=168
168 % 10 = 8
So 71989-17-8 is a valid CAS Registry Number.

Peptide Synthesis. Part 2. Procedures for Solid-phase Synthesis using Nα-fluorenylmethoxycarbonylamino-acids on Polyamide Supports. Synthesis of Substance P and of Acyl Carrier Protein 65-74 Decapeptide

Atherton, Eric,Logan, Christopher J.,Sheppard, Robert C.

, p. 538 - 546 (2007/10/02)

Use of base-labile Nα-9-fluorenylmethoxycarbonylamino-acids in combination with acid-labile t-butyl or p-alkoxybenzyl side-chain or carboxy-terminal (resin-linkage) protecting groups enables solid-phase peptide synthesis to be carried out under exceptionally mild reaction conditions.The repetitive and vigorous acidic treatments required in conventional synthesis are avoided.High-yield syntheses of a decapeptide and of an undecapeptide amide (Substance P) are described using this new combination of protecting groups on polyamide supports.
