134541-34-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134541-34-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,5,4 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 134541-34:
(8*1)+(7*3)+(6*4)+(5*5)+(4*4)+(3*1)+(2*3)+(1*4)=107
107 % 10 = 7
So 134541-34-7 is a valid CAS Registry Number.
