189007-66-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 189007-66-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,0,0 and 7 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 189007-66:
(8*1)+(7*8)+(6*9)+(5*0)+(4*0)+(3*7)+(2*6)+(1*6)=157
157 % 10 = 7
So 189007-66-7 is a valid CAS Registry Number.
