1163693-69-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1163693-69-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,3,6,9 and 3 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1163693-69:
(9*1)+(8*1)+(7*6)+(6*3)+(5*6)+(4*9)+(3*3)+(2*6)+(1*9)=173
173 % 10 = 3
So 1163693-69-3 is a valid CAS Registry Number.
