132940-23-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132940-23-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,9,4 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 132940-23:
(8*1)+(7*3)+(6*2)+(5*9)+(4*4)+(3*0)+(2*2)+(1*3)=109
109 % 10 = 9
So 132940-23-9 is a valid CAS Registry Number.
