1199939-52-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1199939-52-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,9,9,3 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1199939-52:
(9*1)+(8*1)+(7*9)+(6*9)+(5*9)+(4*3)+(3*9)+(2*5)+(1*2)=230
230 % 10 = 0
So 1199939-52-0 is a valid CAS Registry Number.
