Check Digit Verification of cas no

The CAS Registry Mumber 1192707-95-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,2,7,0 and 7 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1192707-95:
(9*1)+(8*1)+(7*9)+(6*2)+(5*7)+(4*0)+(3*7)+(2*9)+(1*5)=171
171 % 10 = 1
So 1192707-95-1 is a valid CAS Registry Number.

Facile method for the synthesis of pyrazolo[3,4-b]-pyrido[4,3-d]- pyrimidine-4-ones via a tandem aza-wittig reaction

Wang, Tao,Zheng, Cai Hua,Liu, Shu,He, Hong Wu

experimental part, p. 3386 - 3398 (2009/12/09)

Fifteen novel pyrazolo[3,4-b]-pyrido[4,3-d]-pyrimidine-4-ones (7a-o) were designed and have been successfully synthesized via tandem aza-Wittig and annulation reactions of the corresponding iminophosphorances 5, phenylisocyanate, and substituted phenols in 60-77% isolated yields. Their structures were clearly verified by infrared (IR), 1H NMR, electron impact-mass spectrometry (EI-MS), and elemental analysis. The results of a preliminary bioassay indicated that some compounds possess inhibition activities against the root of Brassica napus (rape) and Echinochloa crusgalli (barnyard grass) at a dosage of 100mg/L and 10mg/L.
