132549-07-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132549-07-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,5,4 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 132549-07:
(8*1)+(7*3)+(6*2)+(5*5)+(4*4)+(3*9)+(2*0)+(1*7)=116
116 % 10 = 6
So 132549-07-6 is a valid CAS Registry Number.
