129101-37-7 Usage

Uses

(2R)-6-Fluoro-3,4-dihydro-2H-1-benzopyran-2-carboxylic acid is a useful reagent for organic synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 129101-37-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,0 and 1 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 129101-37:
(8*1)+(7*2)+(6*9)+(5*1)+(4*0)+(3*1)+(2*3)+(1*7)=97
97 % 10 = 7
So 129101-37-7 is a valid CAS Registry Number.
