131124-17-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131124-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,1,2 and 4 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 131124-17:
(8*1)+(7*3)+(6*1)+(5*1)+(4*2)+(3*4)+(2*1)+(1*7)=69
69 % 10 = 9
So 131124-17-9 is a valid CAS Registry Number.
