Check Digit Verification of cas no

The CAS Registry Mumber 138174-65-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,1,7 and 4 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 138174-65:
(8*1)+(7*3)+(6*8)+(5*1)+(4*7)+(3*4)+(2*6)+(1*5)=139
139 % 10 = 9
So 138174-65-9 is a valid CAS Registry Number.

LINEAR DISPIRO DECANES AND TETRAZOLINES FROM ORGANIC AZIDES AND HEAVY DIAMINO CARBENE ANALOGUES R2M, M = Ge, Sn

Neumann, Wilhelm P.,Obloh, Ronald C.

, p. 145 - 152 (2007/10/02)

Azides R-N3 (R = aryl, acyl, cyclohexyl), react at -30 deg C spontaneously with the diaminostannylene 1 to give the distannadispirodecanes 2 and 3, or with the diaminogermylene 4 to give the digerma analogues 5.The dispirodecane systems, with an unusual linear combination of three four-membered rings, were fully characterized by X-ray and other spectroscopic methods. 4 gives, with 2 mol phenyl azide, the germatetrazoline 6, whose structure is also evidenced by X-ray spectroscopy.
