27704-33-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 27704-33-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,7,0 and 4 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 27704-33:
(7*2)+(6*7)+(5*7)+(4*0)+(3*4)+(2*3)+(1*3)=112
112 % 10 = 2
So 27704-33-2 is a valid CAS Registry Number.
