290353-55-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 290353-55-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,0,3,5 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 290353-55:
(8*2)+(7*9)+(6*0)+(5*3)+(4*5)+(3*3)+(2*5)+(1*5)=138
138 % 10 = 8
So 290353-55-8 is a valid CAS Registry Number.
