283588-74-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 283588-74-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,3,5,8 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 283588-74:
(8*2)+(7*8)+(6*3)+(5*5)+(4*8)+(3*8)+(2*7)+(1*4)=189
189 % 10 = 9
So 283588-74-9 is a valid CAS Registry Number.
