Check Digit Verification of cas no

The CAS Registry Mumber 127832-98-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,8,3 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 127832-98:
(8*1)+(7*2)+(6*7)+(5*8)+(4*3)+(3*2)+(2*9)+(1*8)=148
148 % 10 = 8
So 127832-98-8 is a valid CAS Registry Number.

SYNTHESIS OF 10-(N'-PHENYL)IMIDOYL DERIVATIVES OF PHENOTHIAZINE, AND THEIR REACTIONS WITH O,O-DIALKYLTHIO- AND DITHIOPHOSPHATES

Kamalov, R. M.,Makarov, G. M.,Yarmukhametova, D. Kh.,Pudovik, M. A.,Cherkasov, R. A.,Pudovik, A. N.

, p. 2382 - 2388 (2007/10/02)

Condensation of phenothiazine with phenyl isocyanide dichloride has given 10-(N'-phenylchloroformimidoyl)phenothiazine, exchange reactions of which with salts of dialkylthio- and dithiophosphoric acids result in rearrangement of the initially formed 10-phenothiazines to 10-thiocarbamoyl>phenothiazines, while reaction with diisopropyl dithiophosphoric acid affords diisopropyl chlorothiophosphate, phenyl isothiocyanate, and phenothiazine. 10-(N'-Phenylethoxyformimidoyl)phenothiazine alkylates dithiophosphoric acid to give 10-(N'-phenylcarbamoyl)phenothiazine, while N2-phenyl-N1,N1-diethyl-(10-phenothiazinyl)formamidine reacts with diisopropyl dithiophosphoric acid, affording the salt N2-phenyl-N1,N1-diethyl-(10-phenothiazinyl)formamidinium O,O-diisopropyl dithiophosphate.
