189044-41-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 189044-41-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,0,4 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 189044-41:
(8*1)+(7*8)+(6*9)+(5*0)+(4*4)+(3*4)+(2*4)+(1*1)=155
155 % 10 = 5
So 189044-41-5 is a valid CAS Registry Number.
