131141-34-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131141-34-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,1,4 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 131141-34:
(8*1)+(7*3)+(6*1)+(5*1)+(4*4)+(3*1)+(2*3)+(1*4)=69
69 % 10 = 9
So 131141-34-9 is a valid CAS Registry Number.
