1190227-34-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1190227-34-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,0,2,2 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1190227-34:
(9*1)+(8*1)+(7*9)+(6*0)+(5*2)+(4*2)+(3*7)+(2*3)+(1*4)=129
129 % 10 = 9
So 1190227-34-9 is a valid CAS Registry Number.
