1263199-68-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1263199-68-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,1,9 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1263199-68:
(9*1)+(8*2)+(7*6)+(6*3)+(5*1)+(4*9)+(3*9)+(2*6)+(1*8)=173
173 % 10 = 3
So 1263199-68-3 is a valid CAS Registry Number.
