190904-34-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 190904-34-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,9,0 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 190904-34:
(8*1)+(7*9)+(6*0)+(5*9)+(4*0)+(3*4)+(2*3)+(1*4)=138
138 % 10 = 8
So 190904-34-8 is a valid CAS Registry Number.
