15091-69-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 15091-69-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,0,9 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 15091-69:
(7*1)+(6*5)+(5*0)+(4*9)+(3*1)+(2*6)+(1*9)=97
97 % 10 = 7
