1188930-91-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1188930-91-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,8,9,3 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1188930-91:
(9*1)+(8*1)+(7*8)+(6*8)+(5*9)+(4*3)+(3*0)+(2*9)+(1*1)=197
197 % 10 = 7
So 1188930-91-7 is a valid CAS Registry Number.
