691879-25-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 691879-25-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,1,8,7 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 691879-25:
(8*6)+(7*9)+(6*1)+(5*8)+(4*7)+(3*9)+(2*2)+(1*5)=221
221 % 10 = 1
So 691879-25-1 is a valid CAS Registry Number.
