174679-03-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 174679-03-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,6,7 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 174679-03:
(8*1)+(7*7)+(6*4)+(5*6)+(4*7)+(3*9)+(2*0)+(1*3)=169
169 % 10 = 9
So 174679-03-9 is a valid CAS Registry Number.
