189082-77-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 189082-77-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,0,8 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 189082-77:
(8*1)+(7*8)+(6*9)+(5*0)+(4*8)+(3*2)+(2*7)+(1*7)=177
177 % 10 = 7
So 189082-77-7 is a valid CAS Registry Number.
