Properties and Applications
Dark purplish red.Check Digit Verification of cas no
The CAS Registry Mumber 94713-29-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,7,1 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.Calculate Digit Verification of CAS Registry Number 94713-29:
(7*9)+(6*4)+(5*7)+(4*1)+(3*3)+(2*2)+(1*9)=148
148 % 10 = 8
So 94713-29-8 is a valid CAS Registry Number.
