290333-67-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 290333-67-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,0,3,3 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 290333-67:
(8*2)+(7*9)+(6*0)+(5*3)+(4*3)+(3*3)+(2*6)+(1*7)=134
134 % 10 = 4
So 290333-67-4 is a valid CAS Registry Number.
