197433-30-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 197433-30-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,4,3 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 197433-30:
(8*1)+(7*9)+(6*7)+(5*4)+(4*3)+(3*3)+(2*3)+(1*0)=160
160 % 10 = 0
So 197433-30-0 is a valid CAS Registry Number.
