154357-20-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 154357-20-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,3,5 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 154357-20:
(8*1)+(7*5)+(6*4)+(5*3)+(4*5)+(3*7)+(2*2)+(1*0)=127
127 % 10 = 7
So 154357-20-7 is a valid CAS Registry Number.
