Check Digit Verification of cas no
The CAS Registry Mumber 132149-70-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,1,4 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 132149-70:
(8*1)+(7*3)+(6*2)+(5*1)+(4*4)+(3*9)+(2*7)+(1*0)=103
103 % 10 = 3
So 132149-70-3 is a valid CAS Registry Number.
