1193377-57-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1193377-57-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,3,3,7 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1193377-57:
(9*1)+(8*1)+(7*9)+(6*3)+(5*3)+(4*7)+(3*7)+(2*5)+(1*7)=179
179 % 10 = 9
So 1193377-57-9 is a valid CAS Registry Number.
