Check Digit Verification of cas no

The CAS Registry Mumber 26958-54-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,9,5 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 26958-54:
(7*2)+(6*6)+(5*9)+(4*5)+(3*8)+(2*5)+(1*4)=153
153 % 10 = 3
So 26958-54-3 is a valid CAS Registry Number.

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

, p. 4025 - 4033 (1999)

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