1258196-34-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1258196-34-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,1,9 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1258196-34:
(9*1)+(8*2)+(7*5)+(6*8)+(5*1)+(4*9)+(3*6)+(2*3)+(1*4)=177
177 % 10 = 7
So 1258196-34-7 is a valid CAS Registry Number.
