Check Digit Verification of cas no

The CAS Registry Mumber 97704-77-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,7,0 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 97704-77:
(7*9)+(6*7)+(5*7)+(4*0)+(3*4)+(2*7)+(1*7)=173
173 % 10 = 3
So 97704-77-3 is a valid CAS Registry Number.

Preliminary chemical study of (2-oxo-1,2-dihydrophosphete(P-W))pentacarbonyltungsten complexes

Marinetti, Angela,Mathey, Fran?ois

, p. 633 - 637 (2008/10/08)

The chemistry of the new four-membered 2-oxo-1,2-dihydrophosphete ring has been investigated in two P-W(CO)5 complexes. All reactions which have been observed take place at the P-C(O) bond. Hydrolysis gives the corresponding open-chain carboxyl
