145841-94-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145841-94-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,8,4 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 145841-94:
(8*1)+(7*4)+(6*5)+(5*8)+(4*4)+(3*1)+(2*9)+(1*4)=147
147 % 10 = 7
So 145841-94-7 is a valid CAS Registry Number.
