1043605-47-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1043605-47-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,3,6,0 and 5 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1043605-47:
(9*1)+(8*0)+(7*4)+(6*3)+(5*6)+(4*0)+(3*5)+(2*4)+(1*7)=115
115 % 10 = 5
So 1043605-47-5 is a valid CAS Registry Number.
