119305-83-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119305-83-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,3,0 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 119305-83:
(8*1)+(7*1)+(6*9)+(5*3)+(4*0)+(3*5)+(2*8)+(1*3)=118
118 % 10 = 8
So 119305-83-8 is a valid CAS Registry Number.
