133830-97-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133830-97-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,8,3 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 133830-97:
(8*1)+(7*3)+(6*3)+(5*8)+(4*3)+(3*0)+(2*9)+(1*7)=124
124 % 10 = 4
So 133830-97-4 is a valid CAS Registry Number.
