904669-36-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 904669-36-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,4,6,6 and 9 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 904669-36:
(8*9)+(7*0)+(6*4)+(5*6)+(4*6)+(3*9)+(2*3)+(1*6)=189
189 % 10 = 9
So 904669-36-9 is a valid CAS Registry Number.
