1187457-64-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1187457-64-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,7,4,5 and 7 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1187457-64:
(9*1)+(8*1)+(7*8)+(6*7)+(5*4)+(4*5)+(3*7)+(2*6)+(1*4)=192
192 % 10 = 2
So 1187457-64-2 is a valid CAS Registry Number.
