Check Digit Verification of cas no
The CAS Registry Mumber 123433-60-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,4,3 and 3 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 123433-60:
(8*1)+(7*2)+(6*3)+(5*4)+(4*3)+(3*3)+(2*6)+(1*0)=93
93 % 10 = 3
So 123433-60-3 is a valid CAS Registry Number.
