Check Digit Verification of cas no
The CAS Registry Mumber 133237-33-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,2,3 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 133237-33:
(8*1)+(7*3)+(6*3)+(5*2)+(4*3)+(3*7)+(2*3)+(1*3)=99
99 % 10 = 9
So 133237-33-9 is a valid CAS Registry Number.

Various di- and trisubstituted (benzotriazolyl)- carboximidamides were used for the preparation of N,N-di-and 1,N,N-trisubstituted 5-aminotetrazoles 3a-e and 6a-d under mild conditions in good to excellent yields.
Fimctlonalized tetrazoles from cyanogen azide with secondary amines
Joo, Young-Hyuk,Shreeve, Jean'ne M.
experimental part, p. 3573 - 3578 (2009/10/26)
Secondary amines react with cyanogen azide at ambient temperature in water/acetonitrile to provide tetrazole derivatives directly. The scope and limitations with regard to steric hindrance of the amine are discussed. Although reaction yields are moderate, 29-81%, the cyanogen azide reactions provide a direct and versatile route to functionalized tetrazoles that: may be especially useful considering the diversity of amines suitable for this transformation.
