317810-27-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 317810-27-8 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 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 317810-27:
(8*3)+(7*1)+(6*7)+(5*8)+(4*1)+(3*0)+(2*2)+(1*7)=128
128 % 10 = 8
So 317810-27-8 is a valid CAS Registry Number.
