773859-57-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 773859-57-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,3,8,5 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 773859-57:
(8*7)+(7*7)+(6*3)+(5*8)+(4*5)+(3*9)+(2*5)+(1*7)=227
227 % 10 = 7
So 773859-57-7 is a valid CAS Registry Number.
