Check Digit Verification of cas no

The CAS Registry Mumber 1637648-89-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,7,6,4 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1637648-89:
(9*1)+(8*6)+(7*3)+(6*7)+(5*6)+(4*4)+(3*8)+(2*8)+(1*9)=215
215 % 10 = 5
So 1637648-89-5 is a valid CAS Registry Number.

Facile synthesis of some novel 6-alkyl or aryl-7H-tetrazolo[5,1-b][1,3,4] thiadiazine

Eftekhar, Melika,Eshghi, Hossein,Rahimizadeh, Mohammad,Bakavoli, Mehdi,Saberi, Sattar

, p. 365 - 367 (2014/07/08)

New bis-heterocyclic thiadiazine derivatives containing a tetrazole nucleus have been synthesised by simple, high yielding routes and characterised by FT-IR, 1H NMR, 13C NMR and mass spectral analysis. The key step in the construction of the sixsubstituted 7H-tetrazolo[5,1-b][1,3,4]thiadiazine derivatives involved the cyclocondensation of sodium 1-amino-1H-tetrazole-5- thiolate with a-haloketones. The radical scavenging activity of the new tetrazolothiadiazines was also investigated.
