Check Digit Verification of cas no

The CAS Registry Mumber 1038998-08-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,8,9,9 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1038998-08:
(9*1)+(8*0)+(7*3)+(6*8)+(5*9)+(4*9)+(3*8)+(2*0)+(1*8)=191
191 % 10 = 1
So 1038998-08-1 is a valid CAS Registry Number.

PtCl4-catalyzed cyclization of N-acetyl-2-alkynylanilines: A mild and efficient synthesis of N-acetyl-2-substituted indoles

supporting information, p. 675 - 680 (2018/01/18)

An efficient synthesis of N-acetyl-2-substituted indole derivatives via direct intramolecular hydroamination of N-acetyl-2-alkynylaniline derivatives was developed. The reaction could be applied to a wide range of substrates employing only 1–2 mol% of PtCl4 as the catalyst to furnish the desired indole products in moderate to excellent yields. The current protocol is efficient, reliable and scalable, and could serve as an important tool for convenient and rapid access to this important class of N-heterocyclic skeleton from readily available substrates.
