Check Digit Verification of cas no
The CAS Registry Mumber 1492664-03-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,9,2,6,6 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1492664-03:
(9*1)+(8*4)+(7*9)+(6*2)+(5*6)+(4*6)+(3*4)+(2*0)+(1*3)=185
185 % 10 = 5
So 1492664-03-5 is a valid CAS Registry Number.
