287969-12-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 287969-12-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,7,9,6 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 287969-12:
(8*2)+(7*8)+(6*7)+(5*9)+(4*6)+(3*9)+(2*1)+(1*2)=214
214 % 10 = 4
So 287969-12-4 is a valid CAS Registry Number.
