33932-89-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 33932-89-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,9,3 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 33932-89:
(7*3)+(6*3)+(5*9)+(4*3)+(3*2)+(2*8)+(1*9)=127
127 % 10 = 7
So 33932-89-7 is a valid CAS Registry Number.
