1374634-75-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1374634-75-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,4,6,3 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1374634-75:
(9*1)+(8*3)+(7*7)+(6*4)+(5*6)+(4*3)+(3*4)+(2*7)+(1*5)=179
179 % 10 = 9
So 1374634-75-9 is a valid CAS Registry Number.
