135979-78-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135979-78-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,9,7 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 135979-78:
(8*1)+(7*3)+(6*5)+(5*9)+(4*7)+(3*9)+(2*7)+(1*8)=181
181 % 10 = 1
So 135979-78-1 is a valid CAS Registry Number.
