Check Digit Verification of cas no

The CAS Registry Mumber 331420-40-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,1,4,2 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 331420-40:
(8*3)+(7*3)+(6*1)+(5*4)+(4*2)+(3*0)+(2*4)+(1*0)=87
87 % 10 = 7
So 331420-40-7 is a valid CAS Registry Number.

The absolute configuration of axinellamine A, a pyrrole alkaloid of the marine sponge Axinella sp., was determined as R by synthesizing its (S)-isomer

Seki, Masanori,Mori, Kenji

, p. 503 - 506 (2007/10/03)

(S)-(+)-Axinellamine A [(2E,4E,6S)-2-(6-methyl-2,4-octadienyl)pyrrole, 1] was synthesized by starting from (S)-(-)-2-methylbutan-1-ol and pyrrole. The absolute configuration of the naturally occurring (-)-axinellamine A, a metabolite of the marine sponge Axinella sp., was therefore determined as R.
