904734-37-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 904734-37-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,4,7,3 and 4 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 904734-37:
(8*9)+(7*0)+(6*4)+(5*7)+(4*3)+(3*4)+(2*3)+(1*7)=168
168 % 10 = 8
So 904734-37-8 is a valid CAS Registry Number.
