317819-09-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 317819-09-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,7,8,1 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 317819-09:
(8*3)+(7*1)+(6*7)+(5*8)+(4*1)+(3*9)+(2*0)+(1*9)=153
153 % 10 = 3
So 317819-09-3 is a valid CAS Registry Number.
