Check Digit Verification of cas no

The CAS Registry Mumber 15966-86-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,9,6 and 6 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 15966-86:
(7*1)+(6*5)+(5*9)+(4*6)+(3*6)+(2*8)+(1*6)=146
146 % 10 = 6
So 15966-86-6 is a valid CAS Registry Number.

Preparation and absorption spectral properties of the nitrogen analogs of a pechmann dye and its isomeric pyrano[4,3-c]pyran-1,5-dione

Irikawa, Hajime,Adachi, Norihide,Muraoka, Hirokazu

, p. 1415 - 1422 (2007/10/03)

Bathochromic shifts were observed by replacement of the lactone-oxygen atoms in a Pechmann dye with nitrogen atoms, while hypsochromic shifts were caused by replacement of the lactone-oxygen atoms in a pyrano[4,3-c]pyran-1,5-dione with nitrogen atoms.
