106319-33-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 106319-33-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,3,1 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 106319-33:
(8*1)+(7*0)+(6*6)+(5*3)+(4*1)+(3*9)+(2*3)+(1*3)=99
99 % 10 = 9
So 106319-33-9 is a valid CAS Registry Number.
