Check Digit Verification of cas no

The CAS Registry Mumber 649885-10-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,9,8,8 and 5 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 649885-10:
(8*6)+(7*4)+(6*9)+(5*8)+(4*8)+(3*5)+(2*1)+(1*0)=219
219 % 10 = 9
So 649885-10-9 is a valid CAS Registry Number.

, p. 9895 - 9906 (2007/10/03)

Novel asymmetric sulfinylzincation of alkynoates has been accomplished via a Pd-catalyzed sulfinylzincation using 1-alkynyl sulfoxides bearing chiral auxiliaries as a sulfinylating reagent. The reaction proceeded in a highly syn-selective fashion, giving
