1304134-67-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1304134-67-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,4,1,3 and 4 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1304134-67:
(9*1)+(8*3)+(7*0)+(6*4)+(5*1)+(4*3)+(3*4)+(2*6)+(1*7)=105
105 % 10 = 5
So 1304134-67-5 is a valid CAS Registry Number.
