Check Digit Verification of cas no

The CAS Registry Mumber 622390-57-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,2,3,9 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 622390-57:
(8*6)+(7*2)+(6*2)+(5*3)+(4*9)+(3*0)+(2*5)+(1*7)=142
142 % 10 = 2
So 622390-57-2 is a valid CAS Registry Number.

Biological activities of α-mangostin derivatives against acidic sphingomyelinase

Hamada, Motoko,Iikubo, Kazuhiko,Ishikawa, Yuichi,Ikeda, Aya,Umezawa, Kazuo,Nishiyama, Shigeru

, p. 3151 - 3153 (2007/10/03)

Deprenyl and benzofenone-type congeners of α-mangostin 1 have been synthesized to understand their role for the inhibitory activity against sphingomyelinase (SMase). While removal of the prenyl group of the right side (11 and 12) caused loss of the selectivity between ASMase (acidic sphingomyelinase) and NSMase (neutral sphingomyelinase), the prenyl group of the left side appeared to increase the inhibitory activities (16 and 17).
