244633-36-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 244633-36-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,4,6,3 and 3 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 244633-36:
(8*2)+(7*4)+(6*4)+(5*6)+(4*3)+(3*3)+(2*3)+(1*6)=131
131 % 10 = 1
So 244633-36-1 is a valid CAS Registry Number.
