1590398-71-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1590398-71-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,9,0,3,9 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1590398-71:
(9*1)+(8*5)+(7*9)+(6*0)+(5*3)+(4*9)+(3*8)+(2*7)+(1*1)=202
202 % 10 = 2
So 1590398-71-2 is a valid CAS Registry Number.
