Check Digit Verification of cas no

The CAS Registry Mumber 1369403-22-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,6,9,4,0 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1369403-22:
(9*1)+(8*3)+(7*6)+(6*9)+(5*4)+(4*0)+(3*3)+(2*2)+(1*2)=164
164 % 10 = 4
So 1369403-22-4 is a valid CAS Registry Number.

New pulvinic acid and phenylalaninol derivatives from the mushrooms Retiboletus griseus and R. nigerrimus

Gruber, Gertraud,Kerschensteiner, Lydia,Marumoto, Ryuji,Steglich, Wolfgang

, p. 675 - 682 (2013)

The close genetic relationship of the mushrooms Retiboletus griseus and R. nigerrimus is supported by the occurrence of the orange-yellow retiboletic acid, resp. its methyl ester, in both species. The structures of these highly substituted pulvinic acid derivatives have been elucidated by spectroscopic investigations. R. nigerrimus also contains two N-protocatechuyl-L- phenylalaninol derivatives, nigerrimin A and B, the first reported occurrence of such compounds in nature. Their configuration was established by the synthesis of nigerrimin B.
