444811-13-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 444811-13-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,4,8,1 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 444811-13:
(8*4)+(7*4)+(6*4)+(5*8)+(4*1)+(3*1)+(2*1)+(1*3)=136
136 % 10 = 6
So 444811-13-6 is a valid CAS Registry Number.
