773897-93-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 773897-93-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,3,8,9 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 773897-93:
(8*7)+(7*7)+(6*3)+(5*8)+(4*9)+(3*7)+(2*9)+(1*3)=241
241 % 10 = 1
So 773897-93-1 is a valid CAS Registry Number.
