138421-75-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138421-75-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,4,2 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 138421-75:
(8*1)+(7*3)+(6*8)+(5*4)+(4*2)+(3*1)+(2*7)+(1*5)=127
127 % 10 = 7
So 138421-75-7 is a valid CAS Registry Number.
