Check Digit Verification of cas no
The CAS Registry Mumber 13966-08-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,9,6 and 6 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 13966-08:
(7*1)+(6*3)+(5*9)+(4*6)+(3*6)+(2*0)+(1*8)=120
120 % 10 = 0
So 13966-08-0 is a valid CAS Registry Number.

Synthesis, Crystal Structure, and Properties of 1,1,3,3,3-Pentaamino-1-oxo-1λ5,3λ 5-diphosphaz-2-ene, (NH2)2(O)P-N=P(NH2)3

Coarse crystalline (NH2)2(O)P-N=P(NH2)3 is obtained from a NH3 saturated CH2Cl2 suspension of (NH2)2(O)P-N=P(NH2)3·NH 4Cl at room temperature. (NH2)2(O)P-N=P(NH2)3·NH 4Cl is synthesized by slow addition of Cl2(O)P-N=PCl3 to a solution of NH3 in CH2Cl2 at -78 °C. Excess NH4Cl is removed by treatment with HNEt2 followed by extraction with CH2Cl2. The crystal structure of (NH2)2(O)P-N=P(NH2)3 has been determined by single crystal X-ray methods (P21/c; a = 1462.8(3) b = 944.8(2), c = 1026.9(2) pm, β= 110.69(3)°; Z = 8). In the unit cell there are two crystallographically unique molecules. They form a three dimensional network by intermolecular hydrogen bonding interactions (N-H...N ≥ 313 pm, N-H-...O ≥ 293 pm). The investigation of the thermal properties shows decomposition with evolution of NH3 above 80°C.
