943148-70-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 943148-70-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,3,1,4 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 943148-70:
(8*9)+(7*4)+(6*3)+(5*1)+(4*4)+(3*8)+(2*7)+(1*0)=177
177 % 10 = 7
So 943148-70-7 is a valid CAS Registry Number.
