Check Digit Verification of cas no

The CAS Registry Mumber 1407973-57-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,7,9,7 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1407973-57:
(9*1)+(8*4)+(7*0)+(6*7)+(5*9)+(4*7)+(3*3)+(2*5)+(1*7)=182
182 % 10 = 2
So 1407973-57-2 is a valid CAS Registry Number.

Chiral separation, configurational identification and antihypertensive evaluation of (±)-7,8-dihydroxy-3-methyl-isochromanone-4

(±)-7,8-Dihydroxy-3-methyl-isochromanone-4 [(±)-XJP] is a natural antihypertensive product contained in banana (Musa sapientum L.) peel. (-)-XJP and (+)-XJP were first obtained by chiral resolution, meanwhile circular dichroism (CD) calculations and chiral synthesis were employed to investigate the absolute configuration. The results indicated that the absolute configuration of (+)-XJP is S-configured and the absolute configuration of (-)-XJP is R-configured. Furthermore, the evaluation of antihypertensive effects in vivo proved that R-(-)-XJP was more potent than S-(+)-XJP and [(±)-XJP].
