Check Digit Verification of cas no
The CAS Registry Mumber 132740-44-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,7,4 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 132740-44:
(8*1)+(7*3)+(6*2)+(5*7)+(4*4)+(3*0)+(2*4)+(1*4)=104
104 % 10 = 4
So 132740-44-4 is a valid CAS Registry Number.
