Check Digit Verification of cas no
The CAS Registry Mumber 183997-71-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,9,9 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 183997-71:
(8*1)+(7*8)+(6*3)+(5*9)+(4*9)+(3*7)+(2*7)+(1*1)=199
199 % 10 = 9
So 183997-71-9 is a valid CAS Registry Number.
