287729-69-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 287729-69-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,7,7,2 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 287729-69:
(8*2)+(7*8)+(6*7)+(5*7)+(4*2)+(3*9)+(2*6)+(1*9)=205
205 % 10 = 5
So 287729-69-5 is a valid CAS Registry Number.
