344332-76-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 344332-76-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,3,3 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 344332-76:
(8*3)+(7*4)+(6*4)+(5*3)+(4*3)+(3*2)+(2*7)+(1*6)=129
129 % 10 = 9
