1190757-91-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1190757-91-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,0,7,5 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1190757-91:
(9*1)+(8*1)+(7*9)+(6*0)+(5*7)+(4*5)+(3*7)+(2*9)+(1*1)=175
175 % 10 = 5
So 1190757-91-5 is a valid CAS Registry Number.
