1378894-54-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1378894-54-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,8,8,9 and 4 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1378894-54:
(9*1)+(8*3)+(7*7)+(6*8)+(5*8)+(4*9)+(3*4)+(2*5)+(1*4)=232
232 % 10 = 2
So 1378894-54-2 is a valid CAS Registry Number.
