193140-99-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 193140-99-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,1,4 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 193140-99:
(8*1)+(7*9)+(6*3)+(5*1)+(4*4)+(3*0)+(2*9)+(1*9)=137
137 % 10 = 7
So 193140-99-7 is a valid CAS Registry Number.
