Check Digit Verification of cas no

The CAS Registry Mumber 1220882-98-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,8,8 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1220882-98:
(9*1)+(8*2)+(7*2)+(6*0)+(5*8)+(4*8)+(3*2)+(2*9)+(1*8)=143
143 % 10 = 3
So 1220882-98-3 is a valid CAS Registry Number.

Synthesis of diketopyrrolopyrrole (DPP) derivatives comprising bithiophene moieties

Stas, Sara,Sergeyev, Sergey,Geerts, Yves

supporting information; experimental part, p. 1837 - 1845 (2010/04/06)

Herein we disclose an easily applicable method for the synthesis of diketopyrrolopyrrole (DPP) derivatives comprising bithiophene moieties, with different substituents on the nitrogen atoms (Me, n-octyl, 3,5-di-tert-butylbenzyl, Boc) and on the thiophene rings (C6H13, C12H25), in good yields and purities. A comparison is made between the previously described method from literature and our more efficient approach regarding number of steps, overall yields and ease of synthesis and purification.
