Check Digit Verification of cas no
The CAS Registry Mumber 129433-04-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,4,3 and 3 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 129433-04:
(8*1)+(7*2)+(6*9)+(5*4)+(4*3)+(3*3)+(2*0)+(1*4)=121
121 % 10 = 1
So 129433-04-1 is a valid CAS Registry Number.
