1187232-19-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1187232-19-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,7,2,3 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1187232-19:
(9*1)+(8*1)+(7*8)+(6*7)+(5*2)+(4*3)+(3*2)+(2*1)+(1*9)=154
154 % 10 = 4
So 1187232-19-4 is a valid CAS Registry Number.
