Check Digit Verification of cas no

The CAS Registry Mumber 250134-35-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,0,1,3 and 4 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 250134-35:
(8*2)+(7*5)+(6*0)+(5*1)+(4*3)+(3*4)+(2*3)+(1*5)=91
91 % 10 = 1
So 250134-35-1 is a valid CAS Registry Number.

The synthesis of phosphonyl pyrazoles

Chen, Hu,Qian, Ding-Quan,Xu, Guo-Xiang,Liu, Yu-Xiu,Chen, Xiao-Dong,Shi, Xiao-Dong,Cao, Ru-Zhen,Liu, Lun-Zu

, p. 85 - 88 (1999)

Phosphonyl hydrazones react with DMF/POCl3 to afford 3-phos-phonyl pyrazoles. Phosphonyl methylene hydrazones react with DMF/POCl3 to provide 4-phosphonyl pyrazoles. 5-phosphonyl pyrazoles are obtained from the reaction of phosphonyl chlorovinylaldchydes with phenylhydrazine.
