444618-61-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 444618-61-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,4,6,1 and 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 444618-61:
(8*4)+(7*4)+(6*4)+(5*6)+(4*1)+(3*8)+(2*6)+(1*1)=155
155 % 10 = 5
So 444618-61-5 is a valid CAS Registry Number.
