Check Digit Verification of cas no
The CAS Registry Mumber 181714-74-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,7,1 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 181714-74:
(8*1)+(7*8)+(6*1)+(5*7)+(4*1)+(3*4)+(2*7)+(1*4)=139
139 % 10 = 9
So 181714-74-9 is a valid CAS Registry Number.
