Check Digit Verification of cas no
The CAS Registry Mumber 171897-74-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,8,9 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 171897-74:
(8*1)+(7*7)+(6*1)+(5*8)+(4*9)+(3*7)+(2*7)+(1*4)=178
178 % 10 = 8
So 171897-74-8 is a valid CAS Registry Number.
