129678-25-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129678-25-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,6,7 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 129678-25:
(8*1)+(7*2)+(6*9)+(5*6)+(4*7)+(3*8)+(2*2)+(1*5)=167
167 % 10 = 7
So 129678-25-7 is a valid CAS Registry Number.
