Check Digit Verification of cas no

The CAS Registry Mumber 143032-90-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,0,3 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143032-90:
(8*1)+(7*4)+(6*3)+(5*0)+(4*3)+(3*2)+(2*9)+(1*0)=90
90 % 10 = 0
So 143032-90-0 is a valid CAS Registry Number.

Synthesis of (+)-8-methyl cercosporamide: Stereochemical correlation of natural (-)-cercosporamide with (+)-usnic acid

Cooper,Wang,Saksena,Girijavallabhan,Ganguly,Chan

, p. 4757 - 4766 (1992)

The absolute configuration of the antifungal antibiotic cercosporamide was established as C-9b-(-)-(S) by correlation with synthetic (+)-8-methylcercosporamide. This was accomplished via conversion of the isoxazole (6) available from (+)-usnic acid. Structure revision of the key isoxazole (6), previously assigned structure (5), is described; some of the 13C-assignments for usnic acid made by previous workers have also been corrected.
