808737-53-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 808737-53-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,8,7,3 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 808737-53:
(8*8)+(7*0)+(6*8)+(5*7)+(4*3)+(3*7)+(2*5)+(1*3)=193
193 % 10 = 3
So 808737-53-3 is a valid CAS Registry Number.
