Check Digit Verification of cas no
The CAS Registry Mumber 4770-31-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,7 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4770-31:
(6*4)+(5*7)+(4*7)+(3*0)+(2*3)+(1*1)=94
94 % 10 = 4
So 4770-31-4 is a valid CAS Registry Number.

Palladium-catalyzed ring expansion of hydroxy methoxyallenylphthalans as a novel synthetic method for highly substituted 4-isochromanone derivatives
Jeong, Ill-Yun,Shiro, Motoo,Nagao, Yoshimitsu
, p. 85 - 89 (2007/10/03)
The palladium(0)-catalyzed ring expansion reaction using hydroxy methoxyallenylphthalans (3) proceeded smoothly to give highly substituted 4- isochromanone derivatives (4), and treatment of commercially available phthalide (5) with lithium methoxyallene furnished two atom ring-expanded endo-benzoxepin-5-one (8).
