868771-35-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 868771-35-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,8,7,7 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 868771-35:
(8*8)+(7*6)+(6*8)+(5*7)+(4*7)+(3*1)+(2*3)+(1*5)=231
231 % 10 = 1
So 868771-35-1 is a valid CAS Registry Number.
