Check Digit Verification of cas no

The CAS Registry Mumber 1397693-64-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,7,6,9 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1397693-64:
(9*1)+(8*3)+(7*9)+(6*7)+(5*6)+(4*9)+(3*3)+(2*6)+(1*4)=229
229 % 10 = 9
So 1397693-64-9 is a valid CAS Registry Number.

Novel approach to biscarbazole alkaloids via Ullmann coupling - Synthesis of murrastifoline - A and bismurrayafoline - A

B?rger, Carsten,Kataeva, Olga,Kn?lker, Hans-Joachim

, p. 7269 - 7273 (2012/10/07)

Unprecedented Ullmann couplings of murrayafoline-A with either 6-bromo- or 4-bromocarbazole derivatives provide highly efficient synthetic routes to the biscarbazole alkaloids murrastifoline-A (6 steps, 66% overall yield) and bismurrayafoline-A (6 steps, 28% overall yield).
