131341-32-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131341-32-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,3,4 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 131341-32:
(8*1)+(7*3)+(6*1)+(5*3)+(4*4)+(3*1)+(2*3)+(1*2)=77
77 % 10 = 7
So 131341-32-7 is a valid CAS Registry Number.
