Check Digit Verification of cas no
The CAS Registry Mumber 952408-30-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,2,4,0 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 952408-30:
(8*9)+(7*5)+(6*2)+(5*4)+(4*0)+(3*8)+(2*3)+(1*0)=169
169 % 10 = 9
So 952408-30-9 is a valid CAS Registry Number.
