169898-34-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 169898-34-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,8,9 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 169898-34:
(8*1)+(7*6)+(6*9)+(5*8)+(4*9)+(3*8)+(2*3)+(1*4)=214
214 % 10 = 4
So 169898-34-4 is a valid CAS Registry Number.
