1139922-15-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1139922-15-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,9,9,2 and 2 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1139922-15:
(9*1)+(8*1)+(7*3)+(6*9)+(5*9)+(4*2)+(3*2)+(2*1)+(1*5)=158
158 % 10 = 8
So 1139922-15-8 is a valid CAS Registry Number.
