132279-71-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132279-71-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,2,7 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 132279-71:
(8*1)+(7*3)+(6*2)+(5*2)+(4*7)+(3*9)+(2*7)+(1*1)=121
121 % 10 = 1
So 132279-71-1 is a valid CAS Registry Number.
