Check Digit Verification of cas no

The CAS Registry Mumber 139424-60-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,4,2 and 4 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 139424-60:
(8*1)+(7*3)+(6*9)+(5*4)+(4*2)+(3*4)+(2*6)+(1*0)=135
135 % 10 = 5
So 139424-60-5 is a valid CAS Registry Number.

SPECIAL FEATURES OF THE CHEMISTRY OF HYDRAZIDES OF ACIDS OF TRIVALENT PHOSPHORUS

Grachev, M. K.,Bekker, A. R.,Nifant'ev, E. E.

, p. 1441 - 1446 (2007/10/02)

The chemical behavior of hydrazides of acids of trivalent phosphorus in reactions involving the addition of sulfur and alkylation is similar to that of the corresponding dialkylamides; however, they display considerably higher reactivity in alcoholysis reactins, including acid-catalyzed conversions.It has been established that 1,3-butylenephosphorous trimethylhydrazide exists in the form of two geometric isomers having trans configurations, which are distinguished by the spatial conformation of the phosphorinane ring.
