285138-19-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 285138-19-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,5,1,3 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 285138-19:
(8*2)+(7*8)+(6*5)+(5*1)+(4*3)+(3*8)+(2*1)+(1*9)=154
154 % 10 = 4
So 285138-19-4 is a valid CAS Registry Number.
