Check Digit Verification of cas no
The CAS Registry Mumber 1320137-04-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,0,1,3 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1320137-04:
(9*1)+(8*3)+(7*2)+(6*0)+(5*1)+(4*3)+(3*7)+(2*0)+(1*4)=89
89 % 10 = 9
So 1320137-04-9 is a valid CAS Registry Number.

Acyl and sulfonyl derivatives of 10-aminoalkyl-2,7-diazaphenothiazines
Morak-Mlodawska, Beata,Pluta, Krystian
, p. 1289 - 1298 (2009)
Reaction of 3,3′-dinitro-4,4′-dipyridinyl disulfide (1) with sodium hydroxide in DMF led to 10H-2,7-diazaphenothiazine (4). N-Alkylation of (4) with phthalimidopropyl and phthalimidobutyl bromides gave phthalimidoalkyl derivatives (5) and (6) which were h
