1189780-91-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1189780-91-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,7,8 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1189780-91:
(9*1)+(8*1)+(7*8)+(6*9)+(5*7)+(4*8)+(3*0)+(2*9)+(1*1)=213
213 % 10 = 3
So 1189780-91-3 is a valid CAS Registry Number.
