Check Digit Verification of cas no

The CAS Registry Mumber 1228646-91-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,6,4 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1228646-91:
(9*1)+(8*2)+(7*2)+(6*8)+(5*6)+(4*4)+(3*6)+(2*9)+(1*1)=170
170 % 10 = 0
So 1228646-91-0 is a valid CAS Registry Number.

supporting information; experimental part, p. 2884 - 2887 (2010/08/05)

A series of novel 4-aryl-thiopyrano[3,4-b]pyran-5-one derivatives were synthesized through an efficient one-pot three-component reaction under solvent-free conditions. This work provides a new series of derivatives of thiorotenone with potential biological activity for biomedical screening.
