1022193-69-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1022193-69-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,2,1,9 and 3 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1022193-69:
(9*1)+(8*0)+(7*2)+(6*2)+(5*1)+(4*9)+(3*3)+(2*6)+(1*9)=106
106 % 10 = 6
So 1022193-69-6 is a valid CAS Registry Number.
