244206-52-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 244206-52-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,4,2,0 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 244206-52:
(8*2)+(7*4)+(6*4)+(5*2)+(4*0)+(3*6)+(2*5)+(1*2)=108
108 % 10 = 8
So 244206-52-8 is a valid CAS Registry Number.
