132454-85-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132454-85-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,4,5 and 4 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 132454-85:
(8*1)+(7*3)+(6*2)+(5*4)+(4*5)+(3*4)+(2*8)+(1*5)=114
114 % 10 = 4
So 132454-85-4 is a valid CAS Registry Number.
