138768-31-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138768-31-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,7,6 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 138768-31:
(8*1)+(7*3)+(6*8)+(5*7)+(4*6)+(3*8)+(2*3)+(1*1)=167
167 % 10 = 7
So 138768-31-7 is a valid CAS Registry Number.
