119183-87-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119183-87-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,1,8 and 3 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 119183-87:
(8*1)+(7*1)+(6*9)+(5*1)+(4*8)+(3*3)+(2*8)+(1*7)=138
138 % 10 = 8
So 119183-87-8 is a valid CAS Registry Number.
