33227-90-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 33227-90-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,2,2 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 33227-90:
(7*3)+(6*3)+(5*2)+(4*2)+(3*7)+(2*9)+(1*0)=96
96 % 10 = 6
So 33227-90-6 is a valid CAS Registry Number.
