141694-15-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141694-15-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,6,9 and 4 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 141694-15:
(8*1)+(7*4)+(6*1)+(5*6)+(4*9)+(3*4)+(2*1)+(1*5)=127
127 % 10 = 7
So 141694-15-7 is a valid CAS Registry Number.
