311768-91-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 311768-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,1,7,6 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 311768-91:
(8*3)+(7*1)+(6*1)+(5*7)+(4*6)+(3*8)+(2*9)+(1*1)=139
139 % 10 = 9
So 311768-91-9 is a valid CAS Registry Number.
