193969-31-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 193969-31-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,9,6 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 193969-31:
(8*1)+(7*9)+(6*3)+(5*9)+(4*6)+(3*9)+(2*3)+(1*1)=192
192 % 10 = 2
So 193969-31-2 is a valid CAS Registry Number.
