1089342-05-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1089342-05-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,8,9,3,4 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1089342-05:
(9*1)+(8*0)+(7*8)+(6*9)+(5*3)+(4*4)+(3*2)+(2*0)+(1*5)=161
161 % 10 = 1
So 1089342-05-1 is a valid CAS Registry Number.
