1043452-91-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1043452-91-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,3,4,5 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1043452-91:
(9*1)+(8*0)+(7*4)+(6*3)+(5*4)+(4*5)+(3*2)+(2*9)+(1*1)=120
120 % 10 = 0
So 1043452-91-0 is a valid CAS Registry Number.
