Check Digit Verification of cas no
The CAS Registry Mumber 923571-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,3,5,7 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 923571-17:
(8*9)+(7*2)+(6*3)+(5*5)+(4*7)+(3*1)+(2*1)+(1*7)=169
169 % 10 = 9
So 923571-17-9 is a valid CAS Registry Number.
