950-34-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 950-34-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,5 and 0 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 950-34:
(5*9)+(4*5)+(3*0)+(2*3)+(1*4)=75
75 % 10 = 5
So 950-34-5 is a valid CAS Registry Number.
