Check Digit Verification of cas no
The CAS Registry Mumber 143332-04-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,3,3 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 143332-04:
(8*1)+(7*4)+(6*3)+(5*3)+(4*3)+(3*2)+(2*0)+(1*4)=91
91 % 10 = 1
So 143332-04-1 is a valid CAS Registry Number.

, p. 7660 - 7663 (1992)
Irradiation of dimethyl 1,4-naphtbalenedicarboxylate (1) with various alkenes 2, and 10a-d is found to give novel 1,8-adducts3, 11a-d, 12a,b,d, and 13b,d. The 1,8-photoaddition proceeds with retention of the stereochemistry of the alkenes in the reactions
