1347761-78-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1347761-78-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,7,7,6 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1347761-78:
(9*1)+(8*3)+(7*4)+(6*7)+(5*7)+(4*6)+(3*1)+(2*7)+(1*8)=187
187 % 10 = 7
So 1347761-78-7 is a valid CAS Registry Number.
