132490-22-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132490-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,4,9 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 132490-22:
(8*1)+(7*3)+(6*2)+(5*4)+(4*9)+(3*0)+(2*2)+(1*2)=103
103 % 10 = 3
So 132490-22-3 is a valid CAS Registry Number.
