844644-08-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 844644-08-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,4,6,4 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 844644-08:
(8*8)+(7*4)+(6*4)+(5*6)+(4*4)+(3*4)+(2*0)+(1*8)=182
182 % 10 = 2
So 844644-08-2 is a valid CAS Registry Number.
