Check Digit Verification of cas no

The CAS Registry Mumber 90317-41-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,3,1 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 90317-41:
(7*9)+(6*0)+(5*3)+(4*1)+(3*7)+(2*4)+(1*1)=112
112 % 10 = 2
So 90317-41-2 is a valid CAS Registry Number.

Nuclear Magnetic Resonance Studies of Chelate-ring Effects in Tungsten(O) Carbonyl Complexes of Poly(tertiary phosphines)

Colquhoun, Ian J.,McFarlane, William,Keiter, Richard L.

, p. 455 - 458 (1984)

Magnetic multiple-resonance experiments have been used to determine the absolute signs of the various (31)P-(31)P spin-coupling constants in tungsten carbonyl complexes of the ligand Ph2PCH(CH2PPh2)CH2CH2PPh2.Apparently anomalous values of these coupling
