1341189-08-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1341189-08-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,1,1,8 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1341189-08:
(9*1)+(8*3)+(7*4)+(6*1)+(5*1)+(4*8)+(3*9)+(2*0)+(1*8)=139
139 % 10 = 9
So 1341189-08-9 is a valid CAS Registry Number.
