129444-47-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129444-47-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,4,4 and 4 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 129444-47:
(8*1)+(7*2)+(6*9)+(5*4)+(4*4)+(3*4)+(2*4)+(1*7)=139
139 % 10 = 9
So 129444-47-9 is a valid CAS Registry Number.
