Check Digit Verification of cas no

The CAS Registry Mumber 76504-02-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,5,0 and 4 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 76504-02:
(7*7)+(6*6)+(5*5)+(4*0)+(3*4)+(2*0)+(1*2)=124
124 % 10 = 4
So 76504-02-4 is a valid CAS Registry Number.

Organic Photochemistry, XXXIX. - Synthesis of Benzo- and Pyridoselenolothiopyrans by Thiol Ester-Thiopyrone Transformations

Beelitz, Klaus,Praefcke, Klaus,Gronowitz, Salo

, p. 1597 - 1603 (2007/10/02)

The four new ring systems 9H-selenolobenzothiopyran, 9H-pyridoselenolothiopyran, 9H-pyridoselenolothiopyran, and 4H-selenolobenzothiopyran are described as derivatives 2a-c and 4a, respectively, which are obtained by photoinduced thiolester-thiopyrone-transformation of the S-aryl selenophenethiocarboxylates 1a-c and 3a, respectively.
