90934-00-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90934-00-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,9,3 and 4 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 90934-00:
(7*9)+(6*0)+(5*9)+(4*3)+(3*4)+(2*0)+(1*0)=132
132 % 10 = 2
So 90934-00-2 is a valid CAS Registry Number.
