138308-92-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138308-92-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,3,0 and 8 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 138308-92:
(8*1)+(7*3)+(6*8)+(5*3)+(4*0)+(3*8)+(2*9)+(1*2)=136
136 % 10 = 6
So 138308-92-6 is a valid CAS Registry Number.
