1187947-49-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1187947-49-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,7,9,4 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1187947-49:
(9*1)+(8*1)+(7*8)+(6*7)+(5*9)+(4*4)+(3*7)+(2*4)+(1*9)=214
214 % 10 = 4
So 1187947-49-4 is a valid CAS Registry Number.
