280766-33-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 280766-33-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,0,7,6 and 6 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 280766-33:
(8*2)+(7*8)+(6*0)+(5*7)+(4*6)+(3*6)+(2*3)+(1*3)=158
158 % 10 = 8
So 280766-33-8 is a valid CAS Registry Number.
