134903-72-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134903-72-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,9,0 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 134903-72:
(8*1)+(7*3)+(6*4)+(5*9)+(4*0)+(3*3)+(2*7)+(1*2)=123
123 % 10 = 3
So 134903-72-3 is a valid CAS Registry Number.
