102939-67-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 102939-67-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,9,3 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 102939-67:
(8*1)+(7*0)+(6*2)+(5*9)+(4*3)+(3*9)+(2*6)+(1*7)=123
123 % 10 = 3
So 102939-67-3 is a valid CAS Registry Number.
