134524-37-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134524-37-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,5,2 and 4 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 134524-37:
(8*1)+(7*3)+(6*4)+(5*5)+(4*2)+(3*4)+(2*3)+(1*7)=111
111 % 10 = 1
So 134524-37-1 is a valid CAS Registry Number.
