1259008-81-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1259008-81-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,9,0,0 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1259008-81:
(9*1)+(8*2)+(7*5)+(6*9)+(5*0)+(4*0)+(3*8)+(2*8)+(1*1)=155
155 % 10 = 5
So 1259008-81-5 is a valid CAS Registry Number.
