132974-91-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132974-91-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,9,7 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 132974-91:
(8*1)+(7*3)+(6*2)+(5*9)+(4*7)+(3*4)+(2*9)+(1*1)=145
145 % 10 = 5
So 132974-91-5 is a valid CAS Registry Number.
