131352-56-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131352-56-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,3,5 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 131352-56:
(8*1)+(7*3)+(6*1)+(5*3)+(4*5)+(3*2)+(2*5)+(1*6)=92
92 % 10 = 2
So 131352-56-2 is a valid CAS Registry Number.
