1904-71-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1904-71-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,0 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1904-71:
(6*1)+(5*9)+(4*0)+(3*4)+(2*7)+(1*1)=78
78 % 10 = 8
So 1904-71-8 is a valid CAS Registry Number.
