244777-34-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 244777-34-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,4,7,7 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 244777-34:
(8*2)+(7*4)+(6*4)+(5*7)+(4*7)+(3*7)+(2*3)+(1*4)=162
162 % 10 = 2
So 244777-34-2 is a valid CAS Registry Number.
