193335-14-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 193335-14-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,3,3 and 5 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 193335-14:
(8*1)+(7*9)+(6*3)+(5*3)+(4*3)+(3*5)+(2*1)+(1*4)=137
137 % 10 = 7
So 193335-14-7 is a valid CAS Registry Number.
