Check Digit Verification of cas no
The CAS Registry Mumber 31806-17-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,8,0 and 6 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 31806-17:
(7*3)+(6*1)+(5*8)+(4*0)+(3*6)+(2*1)+(1*7)=94
94 % 10 = 4
So 31806-17-4 is a valid CAS Registry Number.
