Check Digit Verification of cas no

The CAS Registry Mumber 76808-30-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,8,0 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 76808-30:
(7*7)+(6*6)+(5*8)+(4*0)+(3*8)+(2*3)+(1*0)=155
155 % 10 = 5
So 76808-30-5 is a valid CAS Registry Number.

The photochemical [4+4] cyclodimerization of 2-pyrazinone in the solid state

Nishio, Takehiko,Nakajima, Naoko,Omote, Yoshimori

, p. 2529 - 2530 (1980)

Irradiation of 1-methyl-5,6-diphenyl-2-pyrazinone (Ia) in the solid state gave the [4+4] anti dimer (II) in 100% yield, while (Ia) in a solution phase was inert upon irradiation.
