132972-91-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132972-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,9,7 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 132972-91:
(8*1)+(7*3)+(6*2)+(5*9)+(4*7)+(3*2)+(2*9)+(1*1)=139
139 % 10 = 9
So 132972-91-9 is a valid CAS Registry Number.
