Check Digit Verification of cas no

The CAS Registry Mumber 405171-25-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,5,1,7 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 405171-25:
(8*4)+(7*0)+(6*5)+(5*1)+(4*7)+(3*1)+(2*2)+(1*5)=107
107 % 10 = 7
So 405171-25-7 is a valid CAS Registry Number.

Rearrangements of cyclobutenones. Electrocyclic ring closure and thermal ring expansions of 3-allenyl- and 3-alkynyl-2-dienyl-4,4-dimethoxycyclobutenones

Hergueta, Antonio R.,Moore, Harold W.

, p. 1388 - 1391 (2007/10/03)

Thermal rearrangements of 2-allenyl- and 2-alkynyl-3-(2-ethenylphenyl)-4,4-dimethoxycyclobutenones were studied. At ambient temperature, the allenyl compounds undergo an electrocyclic cascade to give bicyclo[4.2.0]-octadienyl-fused cyclobutenones. These u
