1388148-69-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1388148-69-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,8,1,4 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1388148-69:
(9*1)+(8*3)+(7*8)+(6*8)+(5*1)+(4*4)+(3*8)+(2*6)+(1*9)=203
203 % 10 = 3
So 1388148-69-3 is a valid CAS Registry Number.
