98201-66-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98201-66-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,2,0 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 98201-66:
(7*9)+(6*8)+(5*2)+(4*0)+(3*1)+(2*6)+(1*6)=142
142 % 10 = 2
So 98201-66-2 is a valid CAS Registry Number.

Vanillin and piperonal are each converted into methyl 2,3-dimethoxy-6-methyl-4-(prop-2-enyl)benzoate 12, and this is then elaborated into methyl 4-hydroxy-3-iodo-5,6-dimethoxy-2-methylbenzoate 24, which represents the aromatic unit of calicheamicin γ1I.
