Check Digit Verification of cas no
The CAS Registry Mumber 828273-01-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,2,8,2,7 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 828273-01:
(8*8)+(7*2)+(6*8)+(5*2)+(4*7)+(3*3)+(2*0)+(1*1)=174
174 % 10 = 4
So 828273-01-4 is a valid CAS Registry Number.

A new approach to the synthesis of 3,4-dihydroisocoumarin derivatives
Obushak, Mykola D.,Matiychuk, Vasyl S.,Turytsya, Victor V.
, p. 6112 - 6115 (2009)
A new, simple, one-step synthesis of 3-substituted 3,4-dihydroisocoumarins is developed. The products are obtained by the reaction of o-methoxycarbonyl arenediazonium bromides with unsaturated compounds in the presence of CuBr as a catalyst.
