307548-01-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 307548-01-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,7,5,4 and 8 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 307548-01:
(8*3)+(7*0)+(6*7)+(5*5)+(4*4)+(3*8)+(2*0)+(1*1)=132
132 % 10 = 2
So 307548-01-2 is a valid CAS Registry Number.
