Check Digit Verification of cas no

The CAS Registry Mumber 1021186-01-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,1,1,8 and 6 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1021186-01:
(9*1)+(8*0)+(7*2)+(6*1)+(5*1)+(4*8)+(3*6)+(2*0)+(1*1)=85
85 % 10 = 5
So 1021186-01-5 is a valid CAS Registry Number.

Synthesis of a calothrixin B isomer with a novel 7H-indolo[2,3-j] phenanthridine-7,13(8H)-dione structure

Maingot, Lucie,Thuaud, Frédéric,Sissouma, Drissa,Collet, Sylvain,Guingant, André,Evain, Michel

, p. 263 - 267 (2008/09/21)

Synthesis of an N-protected 2-bromo- 1H-carbazole-1,4(9H)-dione is reported for the first time. We took full advantage of the high polarization and electrophilic properties of this new compound to engage it in a regioselective hetero-Diels-Alder reaction. The resultant cycloadduct was next transformed to an isomer of the naturally occurring calothrixin B displaying a new 7H-indolo[2,3-j]phenanthridine-7,13(8H)-dione structure.
