33986-91-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 33986-91-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,9,8 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 33986-91:
(7*3)+(6*3)+(5*9)+(4*8)+(3*6)+(2*9)+(1*1)=153
153 % 10 = 3
So 33986-91-3 is a valid CAS Registry Number.
