1258955-57-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1258955-57-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,9,5 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1258955-57:
(9*1)+(8*2)+(7*5)+(6*8)+(5*9)+(4*5)+(3*5)+(2*5)+(1*7)=205
205 % 10 = 5
So 1258955-57-5 is a valid CAS Registry Number.
