Check Digit Verification of cas no

The CAS Registry Mumber 1448993-76-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,8,9,9 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1448993-76:
(9*1)+(8*4)+(7*4)+(6*8)+(5*9)+(4*9)+(3*3)+(2*7)+(1*6)=227
227 % 10 = 7
So 1448993-76-7 is a valid CAS Registry Number.

Here comes the sun: Three highly efficient organic sensitizers with sterically hindered fluorenyl units and planar indenothiophene derivatives were designed and synthesized (see figure). Devices based on one of these compounds, JK-303, gave overall conversion efficiencies of 8.69, 9.04, 7.27, and 5.82 % using I-/I3-, CoII/CoIII, polymer gel, and solid-state electrolytes, respectively. These efficiencies are some of the highest reported for DSSCs based on organic sensitizers. Copyright
