130444-54-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130444-54-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,4,4 and 4 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 130444-54:
(8*1)+(7*3)+(6*0)+(5*4)+(4*4)+(3*4)+(2*5)+(1*4)=91
91 % 10 = 1
So 130444-54-1 is a valid CAS Registry Number.
