Check Digit Verification of cas no

The CAS Registry Mumber 212122-45-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,2,1,2 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 212122-45:
(8*2)+(7*1)+(6*2)+(5*1)+(4*2)+(3*2)+(2*4)+(1*5)=67
67 % 10 = 7
So 212122-45-7 is a valid CAS Registry Number.

Synthesis of Thiophene-Substituted 3H-Naphtho[2,1-b]pyrans, Precursors of Photomodulated Materials

Moustrou, Corinne,Rebière, Nicole,Samat, André,Guglielmetti, Robert,Yassar, Abd Errahim,Dubest, Roger,Aubard, Jean

, p. 1293 - 1302 (1998)

The synthesis of 3H-naphtho[2,1-b]pyrans 9-21 linked to a thiophene moiety is described. Two different synthetic approaches were applied to prepare these novel functionalized compounds, and their spectrokinetic properties in solution are reported.
